91 pickup 22re converting to AC

Just put in all the parts to convert my toyota to have ac. however when installing the evap core house under the dash, i fit everything in but now i don't see any wires to plug into the ac amplifier and the other plug-in on the side of evap core house.
If someone could walk me through some steps to get this thing going....then ill have ac!
THANKS!!

You do have the Electrical wiring diagrams for your truck.

I am not really sure if the AC wiring is even in non AC trucks you might need to build your own harness .

When you were getting all the switches why did you not get the harness as well??

Unless you bought all new parts .

I really hate to be the bearer of bad news, but to me that looks like the evap core out of a 4runner. The pickups had a different evap core housing. I have one sitting in my garage, as I am planning on doing the same thing at some point, and the one I pulled was from a pickup and it looks different.

For what it's worth, Ernie_808's Cooling Unit (which is what contains the evaporator) looks just like mine.
