Hi all,

Im new to this forum, and im looking for a few wires to put in a backup siren and my alarm.

First one is the neutral safety wire that is ground when in neutral,
Second is the parking light wire on the switch and is it + or ground trigger,
Last one is the reverse sense wire and is it + or ground trigger

I also need some help troubleshooting the blower motor for the heat in the cab (A/C already deleted) so all im wanting to work is the defrost window vents and the two center vents

Thanks

To install a backup warning beeper, you basically need one hot wire and a ground wire. I would tie the red positive wire downstream of the back light switch Red-Blue going to your backup lights. Run the ground wire to anyplace close to the beeper mounting.

Check your heater tubing going from the heater unit to the vents for correct installation. Is the blower motor working in all speeds?

The blower is not working at all my uncle was the previous owner and he did something aftermarket on it and i nor he can figure out what was done and how to get it to work again. The switches work but not spinning up the motor, i can test it directly but i havent been able to source the correct wiring diagram to know what wires are for what.

May be that the resister is bad. PM me with your e-mail address and I'll send a 81 wiring diagram to you
