I have a 4bolt LS2 90mm style factory throttle body, and an 03 vortec engine with the stock 75mm 3 bolt. I've built an adapter plate out of aluminum to fit it up to the manifold but my question is can the 6 pin connector on the 90mm unit be adapted to function on the stock 8pin connection of the truck unit. They are obviously both ETCs. Someone has had to done this with a head, intake manifold and tb swap on their truck?! Any info or advice will be greatly appreciated!
Thanks in advance,
Lyndon

 

There is a harness available to make that work, you may also need a tach module. Call Richard at West Coast Cylinder Heads, he has the parts you need. You can find his website from the list of Sponsors on the right>
