HOW TO: WORKING CRUISE CONTROL in a AUTO to 5-speed swapped

HOW TO: WORKING CRUISE CONTROL in a AUTO to 5-speed swapped cars.
There is an Inhibitor relay underneath the the stock air box.
Labeled "N&P / Clutch"



Pull out the relay



Now using a short wire and a spade connector at each end,

connect terminal three and four at the harness end, pictured below (Numbers are located on the inside of the relay, match the number to harness connector). See picture.



This causes the ASCD Control Module to think its not in Drive or Neutral, therefore allowing cruise to work.With the jumper in place, I tested my car with a test drive and Cruise control worked normally under every possible condition. The next step to making cruise control factory is wiring the clutch pedal.

Switch on the left is the Clutch interlock switch (aka cant start car with out clutch pedal pressed in), Switch on the right is the ASCD Second Cancel switch in place of metal stopper. What I did is I used the Clutch Interlock switch and placed in place of where the ASCD cancel switch will go (on the right of the picture)

(in this picture I do not have the right switch for the ASCD cancel switch so I ended up using my clutch interlock switch as a ASCD cancel switch and placed the metal stopper where the clutch switch goes)



Lastly all you got to do is wire up the relocated clutch cancel switch (now your Clutch ASCD cancel switch) in series with the Brake Pedal ASCD cancel switch.



THEORY: ASCD System is canceled when the cancel circuit is interrupted AKA circuit is broken. The clutch cancel switch works because when it is pressed in, it is closed thus completing the circuit. When placed on top of the clutch pedal it is always closed when the pedal is not depressed, therefore completing the ASCD circuit and allowing it to function. As soon as you press the clutch pedal in, the clutch switch is opened and the ASCD circuit is opened, thus turning off ASCD system. Same happens at the brake pedal. When both Brake ASCD Cancel Switch and Clutch ASCD cancel switch are connected in series, when either of the switches are triggered, they disable cruise control aka ASCD system.

Enjoy!

Good write up, will look into this. Is your ECU wired up or no? I never wired up my ECU so I can use either the Auto or Manual ECU, and I don't have to deal with the top speed sensor or fifth gear switch.

Another method that I've seen used in the past is to jump the inhibitor switch plug to make drive a complete circuit. That will keep the inhibitor relay from energizing and cutting the circuit.

Basically this is what the jumper wire does, completes the drive circuit at the relay.

I am currently running my stock auto ECU and the Automatic Transmission Control Unit is still connected. I have jumped the black and brown/yellow wire for the car to start and I have my reverse lights wired up to the inhibitor switch plug by the battery fuse box. I dont have any of the Neutral, 4th and 5th position gear switches wired up at all.

Hell, I just realized you have a vert. It's easier to do it your way than to have to figure out a method to run a switch to make the inhibitor plug go from park complete (for top) to drive complete (for cruise).

ill be here for a while!!!!

Does the Automatic Transmission Control Unit really matter if it is hooked up? I still have it in my garage but I pulled it out when installing the pedals(it was in my way). I also left the 5th, 4th and neutral sensors unplugged. I am running the automatic ecu but I have the manual one as well if I needed it.

I ripped mine out completely and it went into the trash can, had I known that it was needed to make cruise control work I would have kept it, but I did my 5 speed swap years ago. I don't need cruise control, but it would be nice at time.

The automatic transmission control unit is NOT where the pedals are, its by the ECU in the passenger kick panel. I am not sure what the box (green box) by the pedals was but I also threw it away and still have cruse control. I have not experimented with removing the ATCU and seeing if cruse control still works. ONE OF YOU SHOULD DO IT!!! The ATCU again is by the ECU in the passenger side kick panel.

The green box is the shift lock control unit. I've had keys get stuck in the lock when that has been removed

[music24]

Isnt there a way to disable the shift lock system by removing something from the ignition lock???

[fiznowler]

I pulled out all the bs that connected the shifter to the key lock. Mine works fine.

If the in depth how to that is on this site told me to rip it out I ripped it out. I just never did the wiring portion because I didn't want to brick my car, and while I am pretty adept at wiring, since I do install low voltage systems for a living, messing with the ECU wiring was not something I was comfortable doing. So if the cruise control module is supposed to be by the ECU, I can't guarantee that it is still there since my cruise control didn't work before the swap.

[music24]

Cruise control Module and Auto Transmission Control Unit are two separate things. None of the online sites tell you to rip out Auto Control Unit or Cruise Control Units. Just the green, shift lock unit that is where the clutch pedal goes. Go ahead and try to jumper the relay and see if that fixes your cruise control problem. If it doesnt work then your issues lie elsewhere.

Good luck!
