Deanoko Posted April 23, 2023 Share Posted April 23, 2023 Hey all, Im in the end stages of installing Electro-cruise into a car that did not have it. There are only partial provisions for it and the dash loom that was supposed to be tucked away because I do have the guidematic with its accy loom IS NOT THERE. I bought the missing underdash wiring I needed from a vendor here, but he pulled it out of a box and the installation photos he took are greek to me. I need to know where the wires from the engagement switch and light go. The photo below shows an open connector socket with 3 terminals which is up to the left of the brake pedal. Does someone have a schematic with color codes just for the cruise system? Lacking that can you give me color codes for these 3 connections circled? I surmise they go to the actuator tied into the throttle linkage. Thanks! Link to comment Share on other sites More sharing options...
Deanoko Posted April 23, 2023 Author Share Posted April 23, 2023 If someone has the white loom plug like the one above I would be interested it it. Link to comment Share on other sites More sharing options...
Riv Eng Posted April 24, 2023 Share Posted April 24, 2023 99% sure that what you circled in red is actually for the standard foot headlight dimmer switch. The upper connector is for the optional guide-matic headlight dimmer and the lower connector is for the standard foot dimmer, depending on which option the car came with. The electro cruise does not pass through this connector. I have a colour coded wiring diagram I can share with you in the morning and some photos of when I cut the electo-cruise out of my 64 (it didn't work and I didn't want it). I may have some left over connectors I can send to you too but you will need to re-wire the connectors. I was not trying to save anything when i cut it out of my wiring harness. PM me for details.

Riv Eng Posted April 24, 2023 Share Posted April 24, 2023 Excerpt from the chassis wiring diagram. Link to comment Share on other sites More sharing options...
Deanoko Posted April 24, 2023 Author Share Posted April 24, 2023 Ah, good to know! Thanks for steering me away from that wrong assumption. I will pm you. Link to comment Share on other sites More sharing options...
Deanoko Posted May 9, 2023 Author Share Posted May 9, 2023 (edited) I think what I need is a photo of this bit from a car with Electro-cruise installed. I have some open slots that get taken by wires associated with it I THINK. RED with white chaser (has an intermediate plug in as well) GREEN with white chaser and WHITE Would be most helpful to have their locations precisely notated.

Deanoko Posted May 9, 2023 Author Share Posted May 9, 2023 Also a Lt Blue wire (shown) from the Guidematic came out of this same connector, and I don't know which one it goes back into. Link to comment Share on other sites More sharing options...
Deanoko Posted May 10, 2023 Author Share Posted May 10, 2023 I found an illustration: fig. 10-159 which appears to show wire colors by connection for these bulkhead plugs which will be helpful. The other question I have is found on the fig. 10-171 chassis wiring diagram, where wire bus connections have letters and numbers below without explanations. Does anyone know the code?

Riv Eng Posted May 14, 2023 Share Posted May 14, 2023 See pic. Cut wires are from cruise, since I removed it from my car during my re-wiring process. Green, white, and red at the bottom. Tan is parking brake switch light (also cut since I am going to E-Stopp) Next up is grey (also part of Cruise) Dark Blue is Speedo Buzzer (also cut because I hate that fricken thing) Link to comment Share on other sites More sharing options...
Riv Eng Posted May 14, 2023 Share Posted May 14, 2023 pretty sure extra Lt. Blue wire goes on the black connector, but not sure where. Link to comment Share on other sites More sharing options...
Deanoko Posted May 14, 2023 Author Share Posted May 14, 2023 The other end of the light blue wire goes directly to the Guidematic fuse in the fuse panel. I'm hunting for where the other end goes. Thanks. Link to comment Share on other sites More sharing options...

Thanks much! That's where I put them!! My green and red have white stripes, but I'm sure since they come from the engage sw that they are the same ones.

Riv Eng Posted May 14, 2023 Share Posted May 14, 2023 Will check my diagram tomorrow and let you know where Lt. Blue goes Link to comment Share on other sites More sharing options...
Deanoko Posted May 14, 2023 Author Share Posted May 14, 2023 I also have an intermediate connection of the red cruise engage sw wire which plugs in somewhere upstream of the final bulkhead connection. That one is still hanging loose. Another fun task tomorrow is modifying the brake pedal arm by drilling it to accept the disengage pin, which sits inside the slot of the switch. I figure that will be easier than trying to swap out the whole pedal from an E-C car. The bracket for the pedal lever already has the 2 mounting holes for the switch, thankfully. It would be nice if there was already a hole in the pedal arm, but no such luck. I'll look closer for a starter divot, but not hopeful there Link to comment Share on other sites More sharing options...

Is this the same as the red w/ white stripe wire, or a separate red wire? Link to comment Share on other sites More sharing options...

Not sure the blue wire goes through this connector. Pretty sure it goes though the other connector (Black one). You may have to unbolt your connector and check the other side for the blue wire lead.

The end of the light blue wire is different from the others, being a flat micro blade male style. Thanks! Link to comment Share on other sites More sharing options...
