4WD won’t engage

Not sure which pin indicates the front driveshaft is locked in. Based on the descriptions, I guessed it’s Pin #26 and tested it. It still reads 11.34v indicating the front driveshaft is NOT locked when the Tranfer indicator switch is jumped. Will it even lock when the truck is sitting still?

 

I meant physically see if it turns with the switch in 4wd, we know the Transfer Case Actuator moved based on TL1,TL2, & TL3 but the 4wd switch didn't close indicating the shift fork moved in the transfer case therefore we want to check circuit integrity and also check that the transfer case is indeed in 4wd which would prove the 4wd position switch is bad.

I hope I'm making sense to you.

 

I checked the driveshaft after jumping the Transfer 4x4 indicator switch. It does lock in! I’m guessing it I pull that switch & test it for resitance it will fail. Not totally sure about that. Replacing the switch should get me back to 100% I hope. The Toyota OEM Switch is $130. Any idea if there’s a cheaper aftermarket part that is reliable?

 

Standard Motor Products makes one but it's still $87.
