Speaking of wiring, you can either trim down a factory wiring harness to work with your TBI conversion or you can buy a harness from the aftermarket. Several websites explain what to trim and what to keep, but we prefer the threads on the topic at Binder Planet (<a href="http://www.binderplanet.com/forums/index.php" title="" target="_blank" rel="nofollow">binderplanet.com/forums</a>). After all, if it can make GM TBI run on an old tractor engine it should work on just about any gas engine. We went with the Standard Length GM TBI new replacement harness from Painless Performance Products (PN 60101, $520).
