Since this is my first post first I'd like to say hi to everyone and thanks in advance for any help you may be able to provide.

I'm building up an 89 F150 Shortbed and I've run into a couple problems. See I swapped out the straight six EFI for a 351W carb engine out of an 85 Bronco. Of course now I have some guages that don't work, and thanks to the wonderful (sarcasm) wiring diagrams in the workshop manuals I have, can't figure out which wires on the old harness connect to the temp and oil pressure relays. Also anyone know how to wire the tach up to this thing?

Please help. I know I could go to seperate aftermarket guages but I just don't like the look of them. I like to have the stock interior look whenever possible.

Hate to bump threads but does anyone have an idea how to do this?

My diagrams don't have those wires. Trace back the gauges on the back of the cluster to the plug and see what color the wire is. The factory tach wire is there too.
