[al_p_gte]

Hi i have a 1989 1.4 sr nova and im for fitting a 1.6 gte engine in to her i need find out a few things.:roll:
1st the wireing
there are 4 wires on the loom
1 heavy red wire
1 black
1 green
1 red over blue wire
Where do i find them on my loom at.:confused:

Where are two fuel pipes on the engine one is at the front close to the block and one is behind it close to the fire wall. What is flow and what is return.

And the last one there is a small air pipe that has three ends two ends go on tha injection system and where dos the other one go to. Dos it go on to the black pipe for the air flow meter.
Thanks to any one who can help me ;)

red wire goes to the thin wire that goes to the starter, black is ignition on, green is rev counter to back of clocks, red over blue goes to fuel pump positive.
I dont get what you mean about the fuel pipes, a pic would help, same with the air pipes really. I'll double check what i have just said about the wiring too, i have it all written down somewhere. Search my old threads for more info on it!
