TB/wiring issues

[lak2004]

The TB I have came off of a Van w/a 350 in it, I think it was a 1990. The wiring harness I have came off of a blazer.

The TPS sensor on the TB has a different plug than what my wiring harness has. Any suggestions?

Should I swap the TPS sensor itself or go for a different connector? Will this TB even work?

Its going onto another TBI 350 engine.

Just swap the connector, the wire colors are the same and it's just a matter of splicing the new pig tail on. The TPSs are not interchangable on the throttle body.

Thought that might be the case. Anybody got a connector that will work? I sold all the harness from this TB.

If you've got one handy, probably a good wrecking yard item, although might be a bit rare.

Napa may be able to help you out, or GM, but with the age, GM might be a longshot.

Personally I'm too cheap to pay for any of those connectors...as in the case of the temp sendors, the connectors can be more expensive than the component they connect to.

Try NAPA number ECH EC89 for around $15.00.

My guess is your TBI has the small round TPS switch? Here is an adapter harness. http://www.turbocity.com/product_info.php?cPath=16_23&products_id=50

Yea it is the small round one instead of the flat one. Thanks for that link that is exactly what I need and cheap too.
