Cruise Control

[YLD-CHLD]

After a couple of long trips in the skyline i have found the need for a cruise control unit.Investigated the aftermarket options & found that about $800 would have one installed. Also found that the vacuum units are not that good so it would have to be fully electronic.Then thought about modifying a cruise control module to work in the skyline!

Checked out how the holden VP-VR ones work & this is what i've come up with.

My understanding of how the module works is that it gets a signal from the VSS, when told to hold that signal(SET) it starts to control the output cable forward or back to get the same signal from the VSS as it was SET at.

The Res+ & Dec- only ask for a preset increase/decrease in the set signal.

Just interested to see if anyone has managed to adapt a vn-vr cruise control module to run in there skyline?

From what i can gather they require the following electrical connections:

1.Ground

2.12v+

3.Speed signal-back of gearbox

4.On/Off -connected in series with the brake peadl switch, & mounted on dash

5.Res + -am/fm button on dash

6.Dec- -scan button on dash

7.Cruise Control on light,mounted next to switchs

8.Cruise in use light,mounted next to switchs(maybe have a dual color LED instead of 2 seperate LED's)

9.Incorporate a switch on the clutch pedal into cancel/resume for gear changes while in cruise control.(Going up steep hills & going down hills)

I'm thinking about doing this and using the radio buttons on the dash as the Res+ & Dec- buttons then mounting a standby/in use/off light.

Taking the speed signal from the back of the gearbox.(May need to be convereted)

Can anyone with any experience or electrical knowledge help with this please?

Not trying to be cheap here just after a great DIY that others may also be interested in & maybe stop a lot of accidental speeding fines.

Can pick up the module & cable from a wreckers for $150, then make up a connection to mount onto the current throttle bracket.

Bit of soldering & wiring ,mount the module & there we have it Cruise Control.

Will attempt to scan the schematics later if that will help anyone.

Those interested please PM or E-mail [email protected]

Thanks All will update this thread with any relevant info.

I fitted a Rostra Electronic cruise control on my R33 then pulled it off and fitted on my R34. Got it from Electric Life in Melbourne. Had for 4-5 years and never missed a beat.

Gotta have one, like you say to stop those speeding fines!

do you know what the pulse rate for the GM item - it will be VERY different.. to do it correctly you will need to mimic the ladder network of the stalk. the buttons on the dash are (skyline) a ladder network also. get the speed right , inputs right and it will work get it wrong - nada.

feel free to ask questions
