Can you still do this with the small bulb method across the coil? Or just a bulb with the coil disconnected? Don’t want to damage the module. I Suppose a volt meter across the coil would do it. Or would you do it watching the spark? This is just for initial start on rebuild engine.
Yes, RED wire on module to coil + ( black ignition power, other power feeds), BLACK on module to coil - (or test light bulb from ignition feed) But it can be fiddly if you have one with adaptive dwell. You have to put the engine at 7 degrees btdc and waggle the distributor back and forwards rapidly. Do this for ballpark timing you will never get it right. Then wire a remote start switch to the starter motor and try to start it then fiddle with timing while cranking to get the timing.
If it’s a Pertronix 1, you can use the light bulb method for static timing. ps ...with coil connected
If its a Pertronix Ignitor II variable dwell unit be prepared for little ignition hiccups if your 12volt wiring is a bit dodgy. And running an electronic module on a worn out distributor can cause strange effects as the friction from points was what stopped it rattling and bouncing at idle.
If it’s the first start with a new cam and lifters get the timing close enough to get the engine running, do the cam break in, don’t let the engine idle, then faff about with the timing and carbs.
