I recently installed a '97 Vortech 350 SFI engine into my '95 Suburban. I got the engine out of a '97 with the wiring harness and I now need a good source for a wiring harness diagram for both the '95 Suburban & '97.

The situation now is that the connector that comes through the fire wall by the heater/AC is different (as well as has less conductors) than the one that is in the dash of the '95 Suburban. The big thing right now with this is the speedometer, tach, & ALDL.

Anyone out there have a suggestion for a website that might have a wiring diagram (especially under dash & ECM) or a source for a printed version?

A little late now, but your best bet is just to buy a haynes manual. They will have the diagrams for both years. This will make it very easy to cross ref the connections.

Best of luck!
