how hard would it be to put the harness from a TPI car into an 89 305 TBI?

 

i'd like to know also

 

somebody please reply that knows how hard it would be, i am going to do the same to my car and i need to know.

 

i'm finishing up my 305 TBI to 350 TPI swap and i'll tell ya it's not easy.but it will be worth it.the hardest part was the fuel pump i spent way to much time in trying to get that ****er out the "right" way.i said **** it and did it the easy way i cut a "access" panel in the body to make it easier to get it in an out.after cuttin gthe access panel i then cut the fuel lines with a small pipe cutter and after i got the pump back in i used compresstion fittings to put it all back together.i'm glad i made a panel because it turns out the new pump that i bought from www.apeusa.com was bad.i got into contact with APEUSA and was told to send it back and he'll ship me out a new one.
now when it comes to the wiring harness i would try and find one that is out of the same year car as yours.or you could go the route i went and have your harness converted.when i bouhgt my motor the harness and ECM came with it,i wanted to go with speed denisty so i needed to have it converted.check out www.chevythunder.com.Leonerd Sparks was very helpful i don't think I could of done it with out him.at least check out his web site there is soooo much info there.
well that's all for now feel free to PM me or e-mail me if you have any questions

 

thanks a lot bandit. let me know how it ends up!

damn. sounds like you are having some problems. that would be my captain obvious statement of the day

 

well i am going to start my swap on monday and i hope nothing like that happens to me. i am getting a holly pump for my car so maybe i don't have to worry about all this. i really need my car to drive around and i cant have it parked waiting for parts.
well good luck man let us know what happens in the end.

 

well i hate to be the one to break it to you but a Holly fuel pump is just a repackaged Walpro pump.open up the nice neat Holly box and you'll find a Walpro pump inside.

Holly(walpro)pump $130ish to $180ish
Walpro pump from www.apeusa.com $103

 

hahaha ya damn that was a close one almoust bought that pump well thanks for the info but just to let you know i am going with a bosch fuel pump capable of suporting 550 hp. i think i will like that one much better then the holly.
