Caseyrhe 650 Report post Posted June 7, 2016 Anybody have a clue what and where this wire connects to? Currently building my recently purchased 69 Mach from out of boxes. So far all lights, all dash instruments/tach, blower motor, and wipers work.....have yet for it to light up with test light. Any help or direction would be great appreciated.

Midlife 814 Report post Posted June 7, 2016 Take the wire nut off and inspect the wire itself: is it a single strand? If so, it is a resistor wire for either the CVR input or for the alternator indicator lamp. If not, it is a brake proportioning valve signal wire. My guess is the former, based upon the violet/white wire nearby, which is the brake line. Quote Share this post Link to post Share on other sites

Caseyrhe 650 Report post Posted June 11, 2016 It's the single strand wire. Any reason why you think it would be cut? Can't fing other end either. Quote Share this post Link to post Share on other sites
Midlife 814 Report post Posted June 11, 2016 It's cut because someone decided to bypass the constant voltage regulator or it simply broke off of the dash cluster connector pin. Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted June 12, 2016 Kinda sorta related, mini hijack alert. Is the constant voltage regulator needed for all cars? I don't recall mine ever having one or removing it during teardown. Having seen my harness MidLife, you should be able to relate. Quote Share this post Link to post Share on other sites
Midlife 814 Report post Posted June 12, 2016 The CVR is needed for factory fuel, oil, or temperature gauges and sending units. Quote Share this post Link to post Share on other sites
