[T3] Chassis Number

[Brion Sabbatino]

Jim, 

Thank you Jim. That is what I thought, a four terminal relay. Sometimes I just need an acknowledgement that I am on the correct track. 

Had eliminated the nine terminal relay and there are two many wires for the three.

I need to go out and see why the ungrounded three terminal relay is even working at all. It is a plastic square bosch unit.

Might be a few days. Winter just hit, windy and cold in the fifties here. Should be nicer by Wednesday.

I will check the housings.

I will get the correct one in any event and mount it under the dash on the plate above the steering column.

Of all the list/groups I am on this is the best most civilized, and helpful group.
