Wiring

[chilsam]

Swapped in a 90 4.0 with an auto harness into a 89 2.9 manual with manual dash wiring,everything i swapped works, problem is now i dont have tail lights reverse lights,brake lights,running lights,dash lights,radio & fan dont work,fuel gauge is pegged at full only the front turn signals work no flash.Headlights,horn,wipers tach & dome all work ?????

Sounds like you missed a connector or two.

Do you know how to use a meter to check for power?
Did you compromise any of the grounds on the inner front fenders?
And of course, check the fuses.

Thanx!

The meter I'm a little iffy on fuses are all good and dash lights do work I've tracked down all the grounds "I HOPE" n are bolted down.Seems my circuits are just dead from the 3 plugs on driver side fender back,also when i turn blower motor on "dont work" the lights in the heater controls go out could motor be shot? Its the 1 out of the donor truck and i never tried to run it.Electrics have NEVER been my strong point. THANX for your time n help!

sounds like wires touching or bad ground for some stuff. id just start tracing wires or use the multimeter.

Thanx!

If & when it stops raining thats what I'll do.THANX 4 your time and advice, "UPDATE" I had to repin 2 of the cannon plugs I now have all lights and gas gauge except brake lights and flashers Dont have back up lights either have power going into switch but none coming out when in reverse "bad switch" gas gauge now works.Gonna go at it again to get brake lights 2morrow and blower motor working when on high it barely works and nothing on other settings short maybe? Just wanna THANK you guys for your input!

Update

I now have back up lights and turn signals still no hazard or brake lights do they share a common power or ground wire? Blower motor still not working either but hav'nt addressed that yet.THANX!!

There is a good possibility your blower motor is just the resistors gone bad, Quite a common problem.
