I need the wiring diagram for 91 4.3 tbi
It would help if you had a specific area you need a diagram for... Like a sensor or something. There are a TON of wiring diagrams.
Get a good manual, the only manual, a Factory Service Manual! AllDataDIY.com is good too.

Like I said, your best bet would be to get a good manual. I cannot get a clear image out of my references for this year. You could also try one of those DVD manuals off of eBay, but your best option is a FSM.
