    Who has done it and what wiring harness did you use? I am interested in keeping the factory harness. What modifications will be necessary? Is there a company the will modify the harness for ease of installation?


    Thanks in advance!

    painless sells a kit. part numbers 60101 is standard length, and kit 60201 is 4 feet extra length.

    Starting my TBI swap next week. Got what I needed off an 88 Blazer, the tbi unit, computer, distributor, sensors and all. and got the harness,pump,chip etc. from Howell. Howell will modify a factory harness but its $$$$ /forums/images/graemlins/tongue.gif

    <font color="blue">Use the factory harness as long as its not all hacked up. You only have to make a few power connections and ground it. I used the factory harness for my TPI conversion, it was actually very easy

    No, I have a TPI I need to sell to you! I have once again changed my mind. I am going to go TBI since I have everything, and sell the TPI setup. I have a fresh set of 305 TPI heads that have had larger valves installed that you can buy when you get the rest of it from me! /forums/images/graemlins/grin.gif
