Yj 32rh wiring lock up converter..
 
Just put in a 32rh in my 93 Yj.. The 32rh came out of a 01 TJ.. Only thing i have to wire up yet..Is there a way to wire up the lockup TC lockup? If so how? There is 2 pins for it.. Thanks

From the 97 service manual

TORQUE CONVERTER CLUTCH (TCC) SOLENOID
The TCC solenoid is only used on vehicles with
three-speed automatic transmissions. When the ignition
switch is in the START or RUN position, it connects
circuit A1 from fuse 3 in the Power
Distribution Center (PDC) to circuit A21. Circuit A21
powers circuit F12 through fuse 11 in the fuse block.
Circuit F12 powers the TCC solenoid . The Powertrain
Control Module (PCM) provides ground for the
solenoid on circuit T23. Circuit T23 connects to cavity
B11 of the PCM.

Looking at the connector diagram looking at the connector the right side is 12v power and the left is to the PCM connection which appears to ground the solenoid. Dont know what would happen if connected backwards

Dont know if the 2001 is the same

does this provide a kinda over drive?.....or just save the converter at speeds?.....i also have a newer 32RH, single pin.....left it unplugged for now

Easiest thing will most likely be just wiring it as a toggle switch, I don't think the YJ computer has a pin for the auto lockup

It will lower rpm 100 - 150
I won't do anything to save the torque converter. It will lower trans oil temp a bit while engaged because it becomes a solid connection- no slip and normal slip creates heat.

Heat shouldn't be a concern because you have an external trans cooler.
You do have a cooler, right?
And by now you should have added a drain plug to the pan and should be doing regular fluid changes.
I drain mine every other oil change or so.
Only about 3 quarts come out unless you let it sit for about a week. Then you will get 4 quarts out. It holds about 8ish quarts empty if memory serves.

Keep it cool and the fluid clean and fresh ant it may NEVER wear out.

yes, i did install a trans cooler, and im thinking of using my old a/c rad as a cooler, because the one i got was a smaller one.
I think bottom line, im going to run a toggle to the TCC, only use it at speeds, and im going to sea foam the trans ALITTLE to ensure TCC dosnt grab when on steep hills.
Timing chain is getting done today, so while Im under it, ill get all this done.
Just finished both drive shafts and both front wheel bearings and U joints......so shes almost done.
Then ill just have to worry about the "ugly" part, but thats a whole new thread.
THANKS ALL for the input

Wiring that relay is an easy job. All the wires are around the bulkhead. Your call.
