Help! R32 Rb26 Into R33 Gtst S2

[Tai_Ter]

Hi There

R32 RB26 into R33 GTSt. Long story short (my project nearly completed) some of you allready know the skyline body wiring (Lights, wipers, speedo, oil pressure guage ect...) runs to the ecu. I obviously allready have the standard R33 GTSt body wiring in the car.

R32 body loom is different and therefor Rb26 wiring loom is different as signals from different guages are sent to different pins of the ecu so the wires may need to be cut and pasted into the correct position in order to make things inside the car including fuel pump, and outside (headlights) work.

QUESTION: Diagram, links, ideas for cutting and pasting/ rewiring the R33 GTST Body loom to suite R32 RB26 so I can have fully operational engine running accessories.

I have searched far and wide with not much luck, I have both service manuals (R33 gtst and R32 GTR) but if somone has a human friendly diagram that actual people can read that would be extremely handy.

Thank you

Just compare the pinouts from the 33 and 32 ecu and make the changes you need.

How are you going to sort out the twin airflow meters?

Unless you swap ecus.

I'd be looking at a 33 gtr ecu and loom.

Then customize that to suit.

He could run a 32 gtr ecu and then jusy mod hes current loom and add to it with whatever he needs.

I have a 32 rb26 power fc, but problem is I cant find the pinouts for stupid body loom

[Tai_Ter]

So I have discovered after pulling the dusty old loom out from storage that the R32 actually has 3 body loom plugs whereas the R33 only has 2 so I am going to have to direct wire them to the correct places. but

still if anyone has one of these diagrams they can send me please

[boostn0199]

They should be in the engine manual have you got a copy?

[Tai_Ter]

yeah i have workshop manuals for both but they are just wiring diagrams and are waaay too complex for the every day person. If I could get my hands on a pinout diagram for the plugs and I knew exactly what pin needs to be swapped to what pin it would be do-able. Otherwise I guess my only other option is to pay somone a buttload of money

[boostn0199]

Ive got the ecu pinout for the r33 gtst in my manual i would of thought the one for the 32 is in there to. I can upload the 33 one if you want?

[boostn0199]

Here are the ecu pinout diagrams I found for rb25 and rb26

[Tai_Ter]

Thanks but I can get the ecu pin out diagram but I am talking about the body loom plugs located inside the car next to the ecu itself and I need to know what wire connects to what, the same plugs that connects your lights, horn, wipers, oil pressure gauge and all of that very useful stuff

[boostn0199]

ahh k, I thought you wanted pinouts. Yeah for what you want you have to decypher the wiring diagrams then.

Can anyone recommend a good auto electrician on the Gold Coast?

Hey mate I've got the perfect guy that does conversion wiring, 1 day turnaround and no need to take the car to him all you need to do is take the loom, very resnobley priced also. although he's located up near redbank plains, if your still Intrested swing me a pm.
