zgeezer Posted January 10, 2011 Share Posted January 10, 2011 I have a 2001 Chevrolet electric cruise control consisting of a black box with pinouts that are wired into the donor vehicle's loom. This is not a DBW unit. My engine is a GENIII Lm7 truck engine with VSS off the automatic transmission. My loom is an older one made by/sold by Street and Performance out of Mena Ak. Can anyone here identify the pin outs on the cruise control box? The engine loom does not provide a VSS source for an electrical tach. I need a good VSS signal for both a tach and this cruise control. Is there any plug that would split the VSS signal at the a/t? Please do not refer me to AutoVox's cruise.... I've used them; they also need a clean VSS signal. Regards. G Quote Link to comment Share on other sites More sharing options...
ezzzzzzz Posted January 10, 2011 Share Posted January 10, 2011 There's a similar CC box in my garage out of a 2000 LS1 Camaro along with factory service manuals for same. I can look at some wiring diagrams I have back at home to try to assist. Are you using the GM ECM for the Lm7? My 4.3 ECM has a pin with the VSS output for driving electronic gauges. My LS1 ECM probably has the same. It would seem reasonable that all of these GM ECMs have such an output. If so, you could simply add that lead to the harness. I've always gutted factory harnesses of unneeded wiring the same most of these aftermarket suppliers do. One time I tapped into the VSS output wiring to the ECM for a signal to drive an Autometer speedo in my Land Rover without any problems. Electrical pins/connectors are available at your local GM dealer. They're usually in a large box behind the counter with lots of weatherpack parts.
