Default P0740 code...TCC circut solenoid.

Ok so for the past two weeks my Check engine light comes and goes...

it will stay on for a day or so, then go off for a day or so.

the code is the p0740(tcc solenoid circut)

Now I found the solenoid for 68 bucks at a local trans mission supply.(after chrystler wanted 274 bucks!!!)

But I am wondering if anyone has an idea of what pins to check off the Trans harness to verify it is indeed bad before I go purchase the part drop the pan just to find out its not bad... dont want to replace the part only to figure out I got a bad trans harness or TCU? not sure where the TCU even is or how to tell if its bad. some advice is welcomed! thanks.

IIRC it was moved to the driver's side by then, up behind the knee panel.
