Need: 93 truck shop schematic for cruisecontrol - The 1947 - Present Chevrolet & GMC Truck Message Board Network

BubbaGreen · 03-19-2002, 11:04 PM

Anybody happen to have a helm shop manaul for
a 1993 truck...I am needing to know what one
wire goes to from the cruise control box,
(the one mounted under the hood)...its a
solid white wire...leads to something under the dash (I am kinda assuming it goes to the
convience center computer, but not sure).
If you can help, I would appreciate it. If
you have such a manual, email me directly and will try to better describe it. Thanks..
PS: I know this is a long shot...

I have a Helm's for a '92, and there were some computer changes for '93, but I'll look into it and see what the cruise setup looks like. I bet it's mostly the same.

Hey gmcblu,
That would be great...
The wire in question is:
WHITE in the 'J' position coming out of the cruise control box (under the hood) and goes inside the cab to a very small 3-pin connector with only this white wire in the 'C' position...The rest of the wires match up with my '89 schematics. Not sure what this does, but my thinking is it signals the convience center to tell it that cruise is either turned on or is engaged. Any help would be greatly appreciated. THANKS!

Checkin' on it...

I'm having no luck finding the cruise circuit wiring diagram. Do you have an '89 Helm's with the diagram in it? If so, in what section is it found?

I thought it would in some way be connected to the VSS circuits, but I don't see any ties to cruise anywhere.

Are you looking in the big white wiring
and schematic book?
-OR-
the shop manual like book....

I found the best info in the bigger schematic book. Page 111~113 from the
"1989 C-K Pick-Up Truck Electrical Diagnosis and wiring diagram" book

Thanks,
dont mean to be too much trouble!

I have the all-inclusive shop manual type book. Helm said that the wiring diagrams are included, and I found everything in there relating to the ECM that I needed to do a factory-correct auto/manual tranny double-swap. But I see no cruise wiring diagrams (in the cruise subsection or elsewhere). If I have it I'll be glad to share it with you but I can't find anything yet.

BubbaGreen · 03-25-2002, 11:35 PM

hum,
I looked into the '89 service manaul that
I have, and it too doesnt have anything on
the cruise circuit...the only real info on
this is in the bigger schematic book which
is a seperate manual. Maybe I can stop
by the dealer here...could get lucky and
look at there book. worked with the Dodge
dealer for the seats I found....
Appreciate your efforts,

Thanks!

gmcblu...
I found some cruise info in the regular
service manual after-all. Its on page 9-3
under the ACCESORIES listed as:
Electro-motor cruise system circuit schematic.

Hopefully will read this note *and* be-able
to find it for me....THANKS!
