Most of the vacuum system does not work. It works to run the climate control fan and other engine components and that's about it. Too many problems, leaks, etc. after 25 years of plastic tubing becoming brittle etc. Also much of it had been disconnected prior to my purchase of the car. It was therefore easier to switch to electric systems wherever possible. Not stock for sure, but it works and works dependably. For purists this is anathema, I know.

OK, I was suggesting to JamesDean that there is no reason to convert his entire vacuum system to electric if it's currently working OK. Based on his post, he is simply trying to add a keyless system to the existing vacuum system. The easiest way to do that is to add an electric actuator to the drivers door only, and let the rest of the system continue to work as designed.

BTW, the vacuum systems in both my 123s work perfectly. The 126s are a little more complicated, but 123s are fairly simple to troubleshoot/repair IMHO. If the PO has already hacked up your system, it may make more sense for you to convert it to electric.

I think that's it, but if you want me to make sure send me an email. The kit was about $60 and included every hardware imaginable, 4 actuators, 2 keyless push button thingys, and capable of dome light, starter disable, etc.

Well gentlemen, I do say, i think ive got it. Actuator is now fuctioning..Your wire colors were correct also. I just have to mount the actuator in the door run the wires...i might hook up the horn and the flashing light thing..perhaps even the domelight bit..im not sure...any suggesttions ? would it be too difficult (at this point i dont know what could be any harder) I have 3 - 4pin relays and 2 - 5pin w/ wires....

Good Work Mates

Hey

I installed the actuator today, ran the wire and got the locking system working...I was thinking about hookin up the horn also. I was also thinking as an "aux" feature i could wire up my city lights (since I dont have then wired into the harness) to the AUX feature...for like finding my car at night or something I dont know...just sounded cool...I dont quite know how to go about that yet but i will figure it out.. I am not sure what was the hardest part of this project..wiring..mounting actuator..laying wires to driver's underside...or maybe it was crimping that power wire into the butt-connector...i couldnt do it...I must have used 6 connectors before i got it soild. Its about 45-50F outsideI am working in my socks (from 4 till 9) in my friend's driveway who just happends to be detailing a car...gettting the ground all nice and wet....mmmm my feet are still cold.

anywy thanks for all the help..i want to pursue those two item above if anyone has any ideas on how just drop em down...

thanks

well.. check this project off...done.. system works perfectly..i am in the process of wiring up my unused city lights as flasher when the car locks/unlocks...i just need a inline fuse and im done. I decided not to hook up the horn as it is unpowered when the car is off anyway.

I also cleaned up my engine..removed the unused vacuum lines going to the valve cover. Removed all that plastic.

Next Project...tail light mod and air cleaner bracket. Hit Man X is shipping me up em parts..I think i am going to find a way to strengthen the air cleaner bracket..re inforce it somehow..ive heard those things go often.

Also in the pipeline are: K1 Spring Kit, Passenger Seat Flex Cable (as soon a i get em from FastLane) after those..new rear speakers for the back deck..im thinking of going with Polk DB650s..I have DB460s in the front dash..should sound pretty well.

I also have to get my replacement trim panels painted before winter hits. I want to get these rust ridden ones removed asap.

well, thanks guys for everything. need anything message me
