Hi Started To Lift Engine Out 300zx Tt ,ecu Is Out But Wiring Harness Will Not Pull Through Hole In Bulk Head.

It Will Not Budge At All,must Be Held Somewere Else As Well.

I Have Cut The Cable Tie Further Up But Still No Joy.

Carnt See Any Further Up ,does Any Body Know If There Is Any Thing Else Holding This,cheers Mark

lol, yes mate this is a bitch to get out.

 

You have to remove the dashboard and then the air con components in order to reveal a metal circular plate that forces the ECU loom down towards the ECU inside the car as it passes through the bulkhead.

 

Remove this panel and hey presto........The dash is easy to take off......

i am taking out 1990 tt engine and putting in a 1995 engine

i have the ecu for it but the wiring harness has an extra connectoin coming of near the airflow meter to a boost sensor which is not on the 1990

on the end of this is a small vacum pipe can you tell me were i should connect it to?

also a couple of small vacum pipes have blanks on which should go to two small metal pipes on drivers side on engine near top which should plumb into valves on drivers side corner bulk head.i would have thought theses could be left as i have ecu for this engine which must have ran with out these,if they are blocked off

cheers mark

To be honest Mark I am not sure about the difference between the looms for later models, the best people to speak to will be one of the traders in their section (See main page), they'll have more experience with different looms. Mines a 1990, although I fitted another loom from a later model and all was OK, a few wires on the ECU for my boost controller were a different colour but it works fine. I've never heard of this boost sensor so I cant comment on its location, sorry.

 

Those two pipes your referring too, a picture will help, email to me rs2000turbo@yahoo.com, or tell me the diameter of the pipes and directions. The only pipes up that end of the engine that I can think you can block off are the pipes to the vacuum tank for the brakes, thats normally done for someone wither wanting a firmer feel to the clutch or if the car has gone through a conversion, Auto to Manual. But then if they were blocked off, that means the vacuum tank is already there?!? Hmm, a pic will really help.....

 

Cheers, Mark.

There is a metal bracket plate on the inside of the bulkhead supporting the harness.

 

You shouldn't have to remove the dash!! Just take out the glove box and the heater components next to the a/c and you can remove the bracket and pull the new harness through.

 

Good luck, it's a fiddly job.
