Why does it need to be a multiconductor...You can get TXL 20awg wire by foot.

They sell 18awg/4channel Gray Stranded CU CL3R Shielded Security Cable at home depot both on a spindle and by the foot. I've used this for wideband, and various sensors/leads for injection and spark. I might have some spare at home, I can double check if you want.

Because it's the Easy Button compared to winding 4-6 single wires together and heatshrinking them (especially if they're all the same color)?

Pysber, I gotta guy from another forum I'm on sending me some aircraft wiring, so hopefully that'll work out. But if not, please lemme know whatcha got. Thanks!

I need help figuring out which wire colours go where in the cruise control vacuum servo actuator, as I am installing cruise control in a car that has none of the wiring for it. The wiring diagram is straightforward enough, the one thing I am missing is the pinout for the connector to the vacuum servo actuator that sits in the engine compartment.

Here's what it's plug looks like:


And here it is in the wiring diagram:



Obviously none of the wiring colours match up (which is seemingly not too uncommon on either side of a connector because why not). The wiring diagram which has the harness colours says pink, blue, green/black and green/yellow. The wires on the little pigtail coming out of the servo are blue/orange, blue/yellow, blue/red and blue/black.
The one thing I've been able to deduce by measuring resistances across the various solenoids in it is that the pink one corresponds to the blue/orange one (as it is "in the middle" of any other pair of connections, common to all three solenoids). That pin is at top/left in the picture.

My car lacks A/C (another thing noone here got for their Miata when new), and has two empty connectors at the front-left of the engine compartment which seem to match the wiring diagram for condenser fan relay and A/C clutch relay. Both of these plugs physically fit the cruise control actuator, so I'll just cut one of them off and splice into my homemade cruise control wiring, but I of course still need to figure out which wire is which.

I'm hoping someone with a cruise-control-equipped NB can just take a peek and see what color wires in the wiring harness matches what in the servo actuator. Mine is a 2002, but I've looked wiring diagrams for a few model years it seems they're all the same.

Alternatively, if anyone has seen a wiring diagram with pin numbers for the cruise control servo plug and either of the AC ones, I would be able to match them up that way. All the ones I have seen though only have wire colours and nothing else.

Ashop manual wiring diagram is better than Mellens.

Brilliant, thanks. I'll try to remember to update here how it turns out.

Yep, this here does the job. So, the mapping turns into (car harness -> actuator)
pink -> blue/orange
blue -> blue/red
gr/y -> blue/yellow
gr/b -> blue/black

Just wired the last bits of the cruise control in, and it works like a charm. My gauge cluster didn't have the cruise set indicator it though (no bulb, no traces on the circuit "board" around the hole, and just black plastic where the light would shine through), so I used the "HOLD" light for the automatic transmission instead. As in "hold speed", or something.

I have the diagram - just need to know what the function is.

Shouldn't the diagram tell you what the function is?
