How-To: adding cruise control >04 and SRT
Posted: Sat Apr 23, 2011 2:50 pm
For the last Neons (NGC, >2004) a cruise control kit has been available, too.
Main differences are
different vacuum lines, a stick instead of two switches (as the steering wheel itself looks different now), the vacuumpump is a bit different (Location of plugs and hose and the mountingbracket), the reservoir is different and sits at the firewall, all plugs at the clockspring are different.
The wiring-harness is exactly the same (the partnumber plug and cableshoes) - but here you get some extra cableshoes to make your wiring fit to the different plugs on the NGC-PCM.
The plug
You could also use a stick e.g. out of an PT Cruiser, but you have to solder different resistors.
As some guys figured out, the kit also fits to a SRT. Maybe you have to make the second bowden wire (from the cruise control) fit, as the SRT usualy needs only the one it originally has.
As I told in my write up for the <03 kit you could be glad to find the cruise control already wired up into your neon. Now I had been such lucky.
If you have you could check that by looking in the area where the pump is located if you have the plug there, at the brake light switch connector, if all cableshoes are in (or install yellow/red and dark blue/ red) and at the clockspring-plug (Pin 6 red/ light green, 7 black), if the are all cableshoes in.
How to route the harness if you haven´t found it you could see at my write-up for <03 as the procedure is the same.
The PCM-Plug is different to the <03 so you have to change them for making them fit.
There are four wires to insert into the third plug (count from the bottom >> C3 << - grey if I remember correctly).
The plug has some "pins" where the cableshoes has to be inserted. You must pull them out.
Open up your plug carefully as much as needed and move the red clip on the bottom so that you are able to insert the cableshoes until you hear a little "click". - 5= light green/ red, 7= yellow/ red, 12= tan/red, 34= red/ light green
Then rebuild your plug and isolate it well.
To change the clockspring the steering wheel has be pulled off..
Therefor the airbag has to be removed - attention - don´t do it yourself if you don´t have any idea how to do that.
There are two screws - on the left and the right.
A 13 mm screw which is glued holds the steering wheel.
The steering wheel itself can´t be contorted as there are two scores to prevent that.
Now you could remove the clockspring - unplug the green plug and carefully lift one hook on the top and one on the bottom of it.
>> Never ever turn the clockspring outside and if it is not installed correctly. It could be damaged.<<
I used the chance to install the SRT-leather-steering-wheel.
By the way - the <03 steering wheels will also fit ...
You have to cut out the notch on the back of the colum, insert the stick and screw it thight with three screws.
The reservoir looks like the one out of a 1st gen but has only one vacuum-socket. It has to get installed at the firewall.
Remove the bracket which holds the bowdenwire on the left and the dummyplug on the right.
You will need the short three-ended vacuum line and you will have to seperate the short line from the other.
In the near of your brakebooster you´ll find the plug where you have to connect your new vacuum line.
Route it behind the compensating reservoir.
plug in the medially plug
Installing just the pump is absolutely easy - two screws, plug - ready.
Now install the new bowden wire into your throttle body shaft
Ready.
