hey guys i need help i have a 89 rs that used to be a 2.8 v6 and has been switched over to a 355 and the guy who did that just cut and spliced in the new wires for the new motor. whats the easiest way to rid myself of all the wires under the hood and just keep the ones i need i will be running gauges so i dont need temp.,oil,volt, ect. i just need the basic wires from the fuse box any help thanks guys =)

 

I assume the new motor is carbed.

Wiring diags will help you trace the colors you can delete: http://www.austinthirdgen.org/index.php?pid=19

Usually, everything from pass side harness gets deleted, and everything from driver side harness stays (that's lights, horn, alternator, fuseblock, etc.

 

thanks for that but i dont know how to read it, but i need to know what wires comming from the fuse box that bolts to the fiewall thanks

 

Maybe you shouldn't tackle the project if you can't read a wiring diagram.

 

That doesnt mean im stupid i just need some help with it

 

Wiring diags show wire colors, and what the wires run to. If you can't read color names and names of components, then you should stay out of it.

Besides - there's nothing from the fuse block area that can come out except FI fuses, and there's really no point in wasting anytime tracing and removing those 2 wires.

 

I didn't say you were stupid. It's not a simple job that someone can give you step by step directions for. Youneed to have some skills.

 

I changed a 89 iroc from MAF to 92 Z28 speed density and it was a major undertaking. You would think most of these harnesses would interchange but they will not. I had to change dash harness, tail light harness, etc. The only harnesses I did not change were the A/C harness and the power window/lock harness. I am a HVAC contracter and I know electrical schematics and diagrams and I still needed help. To change from 2.8 to a V8 you will need a complete harness from another car with what you need. Remember from 90 to 92 they had air bags and also speed density. 89 and older had MAF and a different dash. The rear harness is different on the cars as well. I had to change it since the plug-in is different. I had to hook up the air bag system on my 89 and that is a job in itself. Good Luck.
