Fan temp switch from auto parts store or hawks, etc..

There are a couple threads that list part numbers for specific temp switches.

Your fan should be controlled by the ecm which grounds out the relay. You can simply add a switch or install an aftermarket fan controller. It might be better to have someone burn a new chip with some other modifications to it also.

An 87 TA could have either the LG4 or the TPI motor. LG4 would have been controlled by fan switch in the pass head.

The thermostat temperature should also be changed when lowering the fan "on" temperature.

I use a 190* fan "on" switch with a 180* thermostat and they work very well together.

and you can still control the fan 'on' temp with a switch in the cylinder head. just have to remove the plug that's there and screw it in. with the appropriate switch, of course.
