1986 toyota pickup 22r wiring harness??

[Beeks]

 Hi,  I'm looking for any information on 86 pickup blower switch diagram???  I have searched all over the dash for the power source, I have no power at the switch. I have tried to locate all the fuse connections and can't figure it out, behind the glove box replaced the resistor, blower motor. I don't know if I can wire it some how to basically work, I live in Eastern Ore. and it does get cold. I don't know the best place to tap into for power and I'm just tired of being upside down , inside out trying to figure it out.

According to the FSM, these are the things to look for if the fan doesn't work when the switch is on:

Heater fuse
Heater relay
Heater blower switch
Heater blower resistor
Heater blower motor
Wiring or ground is faulty

There are continuity tests for the switch and the relay.
