Little confused about what you are asking. 1) you have a CJ-7 wiring harness. 2) You have a TJ tub? Are you sure it's not a YJ tub? 3) which heater box and controls are you using in the tub the CJ-7 or the TJ heater box?

Sounds like you need 2 of them crappy diagrams, one for the CJ heater wiring and one for the TJ heater wiring. That way you can hot wire the TJ setup. Otherwise, this is a CJ group, most of us have no intimate TJ knowledge here.

The cj wiring doesn't use a relay, power comes to the switch, then to a resistor on the heater box itself so you can have variable speed, then to the blower motor. motor is grounded to the body.

If your using the cj wiring harness, wire it directly to the blower, and make sure you either hook up the resistor found in the upper cj heater box or cut that wiring out and have one speed.
