AC inop with ac switch flashing on control head assembly

Hello to everyone. I just joined Tacoma world. I've been a die hard TOYOTA fan since l was a little boy riding with my dad in his 85 4x4 p/u. I was a certified auto tech for 21 years. I graduated from the TOYOTA T-TEN program at Bessemer State Technical College. I was a certified dealership tech from 1999-2005. So with that said l have replaced the compressor and clutch, l have at least got it coming on again for a very short while before the sw starts flashing again. I have been looking for hours trying to find out which connector number, wire color, and pin numbers are for the terminals (tach) and (lock in) are of the engine ecm for 2TR-FE. So if someone point me to a good wiring diagram of this. Thanks y'all I would be greatful

 

There is an updated A/C relay to fix this issue.

 

Wouldn't happen to have a new part number to replace the old now obselete number

 

See what part number is on the relay in your truck to see if it already has the updated relay.

 

Welcome to TW!
