hi guys just got a 92 swb sierra with a 97 1.6 fuel injected motor in it. the wiring is not hooked up and im having trouble working it out. ive sat for ages with a wiring diagram and still not quite sure. i have the sierra loom connected so i have lights etc. but i cant get power to the ecu. anyone have a diagram on witch wires from the 1.6 loom i need to join into the sierra loom? ive read you only need about 5 wires hooked up for it to run but witch 5 wires are they =O. cheers

You need power from ignition ON to the two relays. One is fuel pump. One is ECU.
If you get stuck send it to Steve at KillaKustomKables.
If I had more idea of your location than just Australia I would be able to recommend someone close to you.

hay want33s any idea what it is worth to get a loom sorted?

[4x4zook]

forgot to mention my loom was cut wen it was removed from the vitara but im pretty sure after goin through diagram after diagram ive still got all the wires i need. just dont know were to join into the siera loom. and thanks want33s that put me on the right track i reken

I have an idea he is on ebay, do a search and send him a PM he will send you a quote.

Shep.... Anything up to $400 I believe..
He did mine cheaper as I was guinea pig...
It is plug and play once done... I'm sure you could handle it without much hammering...

what coloured wires from the vitara loom need to go to the sierra loom? are they only wires that go from vitara loom the ones from the relays?. so i get power to relays then i shld be on track? i cant work out were to splice in.

any1?

Vit uses some different color's..
Where are you?????
What eng????

Black/white with black/white, thats ign
Black/yellow with Black/yellow thats crank if its manual ecu.
Violet and think yellow trace is constant power.
I sent you a link that should help

bit of an update got both relays clicking, f/p priming but with key in the "on" position for about 30 seconds smoke came out my ecu =O. took the cover off the ecu and all still seems to be fine one of the little wires just got a bit hot. so im guessing its shorting out somewere? any ideas

[4x4zook]

ok. got the engine cranking but the wire in the ecu is still getting way to hot. ideas?

[jonno_racing]

dude i would take it to a auto eleci. sorry to be the one to say it.

[4x4zook]

i new that was comin lol

[4x4zook]

if my f/p isnt connected and the pink wire is just hanging free. wld that cause something in the ecu to draw to much power?

[barney7779]

What color is the wire that is getting hot?


What color are the plugs that go into the ECU?


Still have copies of all the wiring diagrams that i used so might be able to help you out

[4x4zook]

this is whats getting hot. the plugs are 2 blue plugs.

[4x4zook]

ok just checked and have got no spark. will chek dizzy wiring later and hopefully theres a wire not connected causing ecu wire to get hot

[joe5701]

I dont think not having a wire connected will cook a diode in the ecu, more a case of having a wire connected wrong. I aint no expert but I would be taking jonno_racings advice

Mine was White (comp) for constant power and i hooked it to White/Green trace (sierra horn).
With it getting hot try to find which pinout that resister goes to and find what wire colour it goes to. Chances are its hooked to a ground/positive it shouldnt be.

[4x4zook]

so the white wire out of the ecu was constant power not the violet/yellow? maybe ill try that

[4x4zook]

bingo! haha thanx for that the diode thingy isnt getting hot anymore and everything still works just gotta try get spark now. thanx

[4x4zook]

another thing to annoy u guys with is this. is there supposto be a hose from this pipe on the inlet manifold to the intake pipe?

[barney7779]

yes there should be a hose connecting them two pipes



White wire is constant 12V

violet/yellow is check engine light

[barney7779]

PM me your email address and i will email the diagram that i used to wire mine up, My comp had the 2 blue plugs aswell
