First off you need to verify that converter is locking up and in what gear by
pressing lightly on the brake pedal the converter should unlock.
As for wiring the blue wire is the 4th gear switch, in your trans it normally closed until the trans shifts into 4th gear which will not work for your app.
The tan/blk is the ground side of the tcc solenoid with it hooked to ground the trans should lock up in 2nd gear.You will either deal with it like this or you can put a 4th gear switch on valve body or on the side of the trans.
I believe you can buy a kit for summit or jegs etc. might try a google search.
