Hi all,

 

About 6 months ago i bought a second hand race logic traction control system and i am looking to get it installed/install it. The harness appears to be in good condition, with minimal cutting in its removal by the previous owner bar a few wires, and a full write up is available on how to install the unit but the only issue i have is not being 100% sure that the harness is as it should be and with my lack of electrical knowledge i thus would not want to self-install without assurance it is all as it should be and then can follow the guide easily..

Ive tried to find complete wiring diagrams to follow to make sure everything is as should be but cannot find much. Anyone with the unit or who has experience with the unit would be massively appreciated who can help me 1) determine the wiring is all setup ready to go or 2) help me install the unit?

I can offer some cash for your services and cups of teas..

 

Im located in Wales, a mile away from Cardiff

You're kinda close to Jimmer, he could install it possibly?

Yeah, I've contacted Jimmer and he is able to providing the harness isn't hacked up (which i don't think it is) but isn't available for at least three weeks and by then, ill be having to head back to university for final exams - ultimately if there isn't any other options then i will go with Jimmer, I'm trying to see what else is out there as well

I have the RLTC. This is the installation quide for a Z32:

Post some pictures up of the RLTC you have bought.

Will Post photos of the harness and the points of doubt i have! I found that guide and it seems easy to follow - providing the wiring is okay and matches it

Black curled wire - Ground?

 

External from the original wrapping?

 

Assuming red to red? Think goes to Ignition source?

 

On the injector wires, assuming just need to reconnect

 

if this is the injector wiring like I think, there's only 4 wires? Should there be 6?

The the main wires are just cut like in that photo.

 

 

Then there are spare wires which seem to be extensions of the injector wires?

 

Oh I do hate wires ?

Do you have the RLTC installation quide (not the one I posted above)? If you don't I've linked it below. It covers all the wires

and their colours. The most important parts are the white plugs that go into the RLTC box itself. Have you got the launch control

box (small black box with knob on it)?

 

The single wires (page 14 and 15 of guide) are solid red is Ignition source, double black is ground black/white is RPM source.

 

The injector circuit(s) are of the form:

 

 

The wires are cut for each injector circuit. For the ABS connections the wires are spliced.

 

The 8 way multilok connectors you have and are described on page 9.

I believe I have everything I should?

 

I'll do my best to follow the wiring through and see it's as should be, thanks Andrew

After trying to follow the manual i can't be confident that everything is as should be as to me its seems there are discrepancies.. i think ill have to find someone to install it for me :/

It all looks there to me. Group 'A' are injectors input/output. Group 'B' are to ABS circuit. Group 'C' are Black box control.

Group 'D' is diagnosics loom (to a PC).

 

 

By way of reference, this is my install under the kick panel in the passenger footwell.

Thanks for the help Andrew that gives me some more confidence!

I'm going to try and tackle this task over the next few days! If anyone is in the area and wants to help let me know [emoji849][emoji1]

Ah! After studying your photo Andrew I have determined where I was getting stuck. The ABS wires appear to have be re-done by the previous owner

Not following the correct colours with the guide.. is there any chance that you know which pin is the right colours for the guide? Red/green/Yellow/Blue?

It dosn't actually matter. My system did have the four colours for each ABS sensor. However the system is smart enough

to work out which wheels are driven (rear) and which are reference (front) and then left and right. This is covered in the

manual (page 18) "Calibration". You can also setup and check manually (using the Windows RLTC software) which RLTC

ABS channel is connected to which of the four ABS sensors (pages 48-50) "Wheels".

 

If you want the RLTC to do the wheel calibration automatically you will need the calibration adapter (see below). This is

plugged into the diagnostic lead during calibration. Otherwise do the setup manually.

 

 

It is important that the four RLTC ABS sensor wires are run in a four core shielded cable from the RLTC box through the

car to the ABS control unit. The four core shield should be connected to the existing shield from the RLTC harness. This is

to ensure that no electrical interference is introduced to either the RLTC or ABS control units.

Out of curiosity, is this actually a worthwhile mod? Would you recommend it? I can see maybe in a high powered car, but mine will only wheelspin in first anyway when I put my foot down

It came up very cheap for me so I snatched it as soon as I could because the units are very sought after. In my mind it's just a safety feature, if I hit a puddle and get caught out or something of that nature

 

I'm sure you saw Dans tragedy not so long ago and he swears if he had his unit installed it would've been saved

Traction control is not ESP! Not sure it will do a thing to stop you spinning whilst turning too fast, aquaplaning or braking mid corner. Only in a straight line on power or if you boot it half way through a corner. Mind you I guess that last would be pretty useful!

 

I have no experience of TCS in a rear wheel drive car, but it's not great in any front wheel drive car I've had so I personally would be wary of leaning on it.

 

ESP on the other hand you can go nuts with in a fwd, I assume the same is true of rwd

It just stops you potentially being caught out in a scenario like this:

Not sure if actually it could be a hindrance in some circumstances. If you were powersliding (not on purpose) then you're supposed to stay on throttle until you catch it, but if the tcs cut power because of longitudinal wheelspin then I guess it could send you round

Yea that's when it's beneficial

The system works very well. I fitted mine for insurance reasons (my driving ability and unexpected road conditions). The

300ZX TT is a powerful rear wheel drive car and can break away suddenly under power (especially with the turbos coming

on boost rapidly). A number of cars in the Club have been written off or badly damaged over the years and nearly always

as a result of getting on the power too early in a corner and/or slippery conditions.

 

So the two key benefits are:

 

a) In a rear wheel drive car you can use full throttle around a corner with greater confidence that the rear end isn't going to

suddenly break away.

 

b) In wet and slippery conditions the car accelerates as fast as grip allows without skidding all over the road.

 

It is a shame that Racelogic have stopped making them.

Would be good if it works as well as you say it does, but just wanted to point out it's not ESP and once the car does start to slide (say you hit a bump and it unsettles the rear end) then you're on your own!

 

Are they Z32 specific?

 

Sent from my SM-N910F using Tapatalk

You are quite correct they are different systems. Racelogic sold thousands of RLTCs so there are many advocates. They

are not specific to the Z32, so you can buy a s/h system and fit it to a Z32 (even if it came from a 4 cylinder car) as two

models were made - 4/6 cylinder and 8 cylinder.

 

The product details are still published on RL's site:

Okay made good progress but hit a road block! Where is the ABS unit in my LWB [emoji23]?

On the rear, the left hand side, where the left rear speaker is.

On the rear, the left hand side, where the left rear speaker is.

Right hand side unless its opposite for US specs?

The ABS control unit is on the right hand side behind the drivers seat 3/4 trim panel as shown

below (the location of the ABS actuator is also shown for reference).
