I have got two Nissan replacement injector looms, three connectors on each one, but only two wires coming from them, where do they connect to on the old loom, I can't see where they go. Have looked in FAQ with no luck, can someone point me to a fitting guide.

 

cheers Paul

Hi Paul, the injectors are sequential so need a feed each. You will have to split the loom and terminate each injector pair to the original loom. Ive had to do the same with my spare engine.

Just mark each one with tape and number, 123456, same as the firing order on the coil packs. Solder and heatshrink each pair, the thicker wire on the injector to the red stripe thicker wire on the loom of the new one.

 

IMO they shouldnt be called a loom, just replacement connectors with some wire on them lol

HTH

Thanks Graham, I only bought this kit because I thought it was a plug and play loom, the description is totally misleading.

Me too lol, but at least you get new connectors and although you have to split the loom back, which is the pain, for me it was easier with the engine on a stand and under the plenum. Although i have the wiring in the engine bay to look forward too :mad2:

Graham have you got any top tips when soldering, should I twist the wires together before applying the solder.

 

Paul

Hi Mate, Sorry just watching the soaps lol.

 

Twist together opposing each other so that when they are soldered together you dont get a ridge, otherwise the heatshrink wont slide over. Place the soldering iron under the twisted pair to build up the heat then apply the solder so it flows into both twisted wires, dont dab the soldering iron, keep the heat on till it flows.

 

Get a heatshrink kit like this http://cgi.ebay.co.uk/127pc-Heat-Shrink-Wire-Wrap-Cable-Sleeving-Tubing-Sets-/280695278660?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item415abe0c44

 

Place some heatshrink over each pair of wires away from the heat before twisting and soldering and a larger diameter that will cover the pair. So 3 pieces per wire/join.

When soldered slide the smaller diameter pieces of heatshrink over the join and heat, using a cigaretter lighter, once both joins are covered, slide over the larger diameter heatshrink over both and heat again. You should have a nice sealed and isolated join.

 

Now repeat 5 more times and job done lol

How much was the new loom??

About £52 for the 2 sets of three

where from

FWIW I bought these from ebay, (great service as well)

should help with tucking the wires under the plenumn by adding the connector/s with the extra bit of wiring on them

just found these

Thats a good deal Howard, i could do with some coil pack connectors a couple of mine have disintergrated and i gave some spares away before i knew it lol

Yes thats about the same price, you need 2 of those if replacing all 6

and about a week wait to get them as well

 

 

£83 quid for the lot from other link

These are what I have just bought, took about a week to arrive.Should have read the description properly.lol

 

You will need a pack of heat shrink, soldering iron, solder, electrical tape and cable ties, you do get 6 cable ties and heat shrink with the kit but you will need more heat shrink as it's not enough.

Why do these repair kits only have 2 wires for 3 injectors?

doesnt matter as your gonna chop the plug and wire to solder in to your loom

each plug would have about 8" of wire to use

 

Mark

No idea, its how they come, once split there are 3 pairs of wires to splice in, i guess its a way of selling new connectors with a bit of wire on lol

i have found these plugs .. 2.99 >3.95 per plug
