Good Day I am in need of a TCA (thermo control amplifier) connector I believe its on the M67 on the harness its connected to the Evaporator unit to the left (going to towards center). I need it for a retrofit of R134a. I need just the connector and a few inches of cable. Please note it won't be on an Auto Air system if its a 90-93. it has to be a manual system or R134a system.
