i bought a 350tpi engine with the computer and harness under the hood. are the computer harnesses inside the vehicle different between the tbi to tpi? cause im going to the yard saturday and want to pick up a harness inside from the computer to the firewall. thanks

 

Dash harnesses are similar to a point

V6 and TPI's interchange

You much match trans type. TBI harnesses are slightly different regarding the VSS

 

ok well this is what im doing. i have a 1992 rs 305tbi auto. and im taking the auto and engine out. and installing a 5 speed and the 350 tpi. and im looking to put the tpi computer in the car... will the 305 tbi/ auto harness plug into the tpi computer?

 

No

Do a search on TBI to SD TPI wiring conversions and then check out auto to T5 wiring conversions. You're doing both

 

what is sd tpi

 

Speed density

 

ya i figured it out as soon as i sent it. im going to the yard to find some stuff and im hpoing to find everything i need right now
