Just finished doing a head-gasket on my truck and am having trouble finding where a few of the plugs connect too

truck is '91 22re w56
although im finding some of my parts i have to get from a later truck, such as my coil/plug wires have to be from a '93 style with the smaller clip on style wires. So im not sure if the previous owner swapped motors or transmissions everything seems factory..

The plugs on wiring harness i cannot find.

#1 near the back of intake manifold i have this one with one blue wire and one brown. im not seeing where it would connect to .



#2 near the transmission . It is pretty long and and i see no where for it to connect either.




My backup lights are not working but i think i have those connected right, im thinking the wire is broken right at the connector for that where it looks kinked.

 

first plug looks like the A/C idle up plug ...
second wire looks like the speed sensor plug .. should plug in on the end of the transfer, passenger side .



.

 

thanks, It looks like you are right.

I have no ac so the plug is just extra .
My speed sensor in the transfer case had been swapped over to the mechanical cable type to be compatible with my dash speedometer .
I noticed the plugs seemed dirty inside the connector so I thought mabey they were never connected but wanted to be sure
Thanks again
