The cold start switch harness is a separate harness without a relay. The harness has two wires (BROWN AND A RED/WHITE) in the harness, one end of the harness terminates at the valve/switch and the other at the timer box on the bulkhead/firewall. The brown wire may stop along the way to a ground point on the bulkhead/firewall.

The timer box in conjunction with the temperature time switch tell the cold start valve/switch when to turn off and on and duration.

If you want the correct boot for the wires at the valve/switch, it is in the parts catalog, 3.0 csi car. The catalog does not show it in the 2002tii section. This maybe the part number 61 13 1 352 793.

Does the valve operate on 12 VDC? I may hotwire until I locate the timer

and harness.

Thanx-Mike

Here is a new wiring harness for the cold start valve and thermo time switch. I also purchased the new sealing boot that Bill Williams mentioned (it doesn't come with the new harness).

I just bought the new harness protector boot from BMWNA, to install it over existing harness, do I have to detach all 6 leads and fish them thru or will the small end of the boot fit over the end connector at the CS valve?

Thanks

BTDT (having made bunch of these harnesses using all BMW parts and the boots mentioned above) you are better off removing the female sockets/pins inside the white connector. The pin removal tool is available here cheap: http://www.vintageconnections.com/

A more expensive version of the tool (German made) is available from Eeagleday.com as well. Alternatively, you can make a tool using a copper wire

and flatting it so I was told.

ps. To be clear, boot goes over the small white connector, not the 6-pin connector that goes to timer on firewall.

Enjoy.

Sorry to bump this but someone ripped the wires out of my connector to the cold start injector. I know that there are only 2 wires and I got the connectors out to re solder them to the wires. Can someone please post up a pic of this connector so I can see which wire goes where?
