Question:
My ’72 tii temp time switch electrical connection (plastic plug end) has snapped off from wire fatigue. Are there any pigtails that I can splice into the wiring harness? Any there other solutions to make the connections down in the cup of the switch?
Answer:
Other than carefully stripping each wire and mounting individual female spade connectors, we’re not aware of anything available that retrofits that connector unfortunately. BMW did use that same connector for Tii and later model cars fuel injection systems using a similar Bosch thermo time relay box. The entire cable setup including the connector you have which failed, and the other wires which reach a ground, the sender on the water tube and cold start valve on the throttle body is still available new from BMW. The part number is 61 12 1 354 671 and the current list price is $62.00. It is shown as item 13 below.
The protective rubber boot for the 2-prong connector is # 61-13 1 352 793 from BMW (Mobile Tradition). For some strange reason, it’s not listed for the tii, but under the 3.0 series cars. My thanks to Bill Williams for this tip.
