Hi Donny, I am having a brain fart....I have one wire coming from my 4th gear solenoid.it is internally grounded..so my problem is I am running a relay and it is also hooked up to the brake light switch..can you tell me how to run the wires.I know the relay has a 12 volt power and a ground wire hooked up to it..how do I wire it. The brake light switch has 2 separate wires,besides the actual brake light hookup..please advise..after this my wiring job is done! Woo.hoo! I installed one of your classic update harnesses..thank you
Dave Souza

Good job Dave!

Without knowing who's trans set up you are using, that is a tough one to answer, but I will try. Several different manufacturers operate that connection a few different ways. Our kit works off a pressure switch and has no interface with the brake switch. If yours is using the brake switch to make or break the feed to the trans, you must first be sure you have a switch with 4 blades, not the usual two. Two are "normally open", and the other two are "normally closed". Is this what you have? If so, our orange and white go to the normal open pair of blades, and when you step on the pedal and the button pops out, the connection is closed and the the brake lights come on. The other pair that are normally closed should have a 12v ignition fused feed going to one blade, and the mate should have a wire that continues down to, and mates to your trans wire. That way, whenever the key is one, you have a feed to that trans. When you step on the brake pedal, it breaks the connection to the trans which should release the converter and OD.

Check with whomever you got your trans set up from to verify this first though please.

Donny
