Right now i have a TPI interior harness but i have a throttle body engine so things arnt working right between the harnesses?? If i found a interior harness from just a carberated would that work with the throttle body exterior harness or do the interior and exterior harnesses have to match?

 

What's not working right?

 

windows.....Door lock...Ignition....and radio...but the ignition is the big one.

 

Why did you switch the interior harness? You're not planning on doing a tpi swap are you?, cause if you are, you didn't have to switch the interior harness. You checked out all your fuses right?

 

When i got the car it didnt have an engine and it hard a tune port before but i didnt have the money to spend togeather a TPI so i put a throttle body in instead!

 

So now i think i have to switch to a different harness for the inside like one out of a throttle body car

 

Ok when You switch different engines you will only need to change the harness for the engine. It is on the passanger side of the car. The engine Harness ties into the Body harness by the Check Engine Light or SES and power and Ground. Other than that There is absoletly no need to change the body harness unless you have a lot of broken wires or a Fire. I would E-mail S10Wildside and he should be able to help you out.

He has a lot of diagrams that will show you where the enging harness connects to the Body harness.

just .02

 

So why wouldnt the ignition be working??

 

A bad fusible link off the starter. It seems that the only things that don't work, are those that operate only when the key is in the 'ON' or 'ACC' position.

 

so how can i fix that?

 

So it shouldnt matter what i have for an interior harness as long as the exterior one fits the engine?

 

Correct. Just check for broken Wires and get out you Chillitons or hayes and check the wiring diagrams to find out where the problem lyes

 

ok, Thanks guy!

 

Do I need to change the wire on the exterior harness or the interior or both or what?? Can anyone help?

 

Maine , i am just trying to help you out here, so bare with me......You said you put a different motor in the car..... Did you or did you not change the interior harness? I was thinking VATS but if yours is an 86' and you didn't change the interior harness it definitly can't be that.

 

i didnt change the interior harness the car use to have a tune port but the kid destroyed it and took it out so when i got it there was no motor in it...So I put a TBI in it out of an 88 camaro...

 

Maine...you don't have to change a thing, just have to do what the others above have suggested.....check the wires going to the ignition and any wire ignition related for broken wires ...etc..... PITA , but it's about your only option right now.

 

so it could be either on the interior or the exterior??? That is the wires that i have to check?

 

Well since all your problem seem to be interior related , i'de start there first. And pull the fuse panel down and check the contacts going in. Ikept blowing fuses one time ,couldn't figure it out for the life of me, pulled the fuse panel down and at some point when i was working on my car i must have dropped a metal clip down on it and it was laying on the terminal that was blowing and another one , found the problem that way.

 

none of the fuses in the fuse box are blown i checked all of them
