Hi, Just wondering if anyone can tell me what voltage the PCM sends to the TCC solenoid to activate it... been trying to hook up a switch to be able to shut it off when I don't want it. I split to TCC wire at the plugin at the transmission and ran it up to a normal off/on toggle switch, but now I have nothing at all for convertor lockup when I switch it on. :aresehole: Was thinking maybe that the solenoid only runs on a couple volt instead of 12v, and between the wire and the switch I've maybe created to much resistance or something..... any idea's out there??
