hp500 carb cant find timing mode wire!
Ok im beating my head against the table here! I have a 95 HP 500 carb with the thunderbolt dist. with 2 wires coming off it (white/red and white/green).
everything i have seen says there is a purple/white wire you need to ground. I have no purple/white wire. Every wiring diagram i have seen does not match what i have either.
does anyone have a wiring diagram for a 95 hp500 so i can verify this thing? The PO replaced the motors so there is a chance its wired incorrectly.
i have a wierd feeling that its already in timing mode because if you run the throttle up the timing doesnt change.....im pretty sure it should kick the advance once over 3k.
can anyone point me in the right direction...or atleast point me to some wiring diagrams for this motor?
thanks

That year will have a TB IV ignition and you do not need to put it into base timing mode.
It should have a V8-HP module which gives 20* advance by 3000rpms. Set base timing at 12-14* and check timing at 3000+rpms.
