All the wires you need are easily accessible from the top of the engine.

While the key is in the start position, power will be sent to the cold start valve if the Thermo-Time Switch allows it. On the left side chain cover is the Thermo-Time Switch which is the basic control for the enrichment solenoid during the starting phase. If the car is warm from running recently, or enough time has elapsed since it was started, the Thermo-Time Switch will interrupt the power going to the cold start valve.

The cold start valve itself has a gray and white wire and a red and black wire from the thermo-switch: Note that the gray and white wire and the yellow wire are connected to the same terminal on the thermo-switch. The WUR (warm up regulator) mounted on an intake runner base on the driver's side of the engine should have a single red wire with white stripes connected to it.

Cold start valve circuit: There should be a wire from the ignition switch to terminal 50 (this is a small blade type lug that receives a female type connector) on the starter, from terminal 50 of the starter a wire (yellow) goes to the throttle valve switch. From the other side of the throttle valve switch a wire (also yellow) goes to the thermo-switch on the driver's side chain case, this wire from the throttle switch attaches to one terminal (this is the non-ground side terminal) of the thermo-switch, a second wire is also attached to this same terminal of the thermo-switch and goes to the cold start valve. From the other side (ground side) of the thermo-switch a second wire goes to the cold start valve.

I hope this isn't too confusing - I stole from previous posts originally done by Jim Sims and Warren Hall (you can't get any better than that). If you get lost, I can help by tracing wires or showing pictures from my car.
