My car currently has no engine installed tho I have 4 on hand .. a supposedly freshly rebuilt 1.7, a 2056 w/ 40idf webers, and a couple of H6 Subarus.

I’m probably gonna pop the 1.7L in first, and move down the line so to speak, as time and money permit. I haven’t paid any attention to the 1.7L since I acquired it
Several years back now. So looking it over today I discovered that it’s points have been replaced with some sort of digital(?) electronic set up. I assume it’s probably pertronix but I have no paper work. Looks like it’s never actually been fully installed either - red and black wires are clean cut on the ends. Can anyone identify this for certain?

Another shot :

Pertronix II ~

I’m skeptical as the front edge of the red module on pertronix units seem to have a couple of angles where as this one is just flat (a more square box). But I guess it’s kind of a moot point since they are more than likely the same things. I’m thinking maybe this is by “Hot Spark”, will need to investigate further.

But basically - this unit’s red wire gets hooked to the + on the coil and the black to the coils’s negative input, right? Am I correct that no other switched wire is needed to be run? (there’s a bk/pu switched wire going to the coil’s + already).

Get the 123ignition! They make a version for every 914 config. It’s awesome!!

Yeah I’m aware that everyone likes it. But I’m not gonna get one of those at the moment, I’m not sure which engine I’ll settle on. Also, somewhere packed away I have an SVDA flamethrower distributor too - I have no idea if that’s on par with the 123 (I don’t think so), but it may be better than this currently installed piece .

Get an engine in and drive it. If it's a 1.7 great....worry about what's best later.

IMHO.

I agree, yea I’m not trying to switch out this unit from the 1.7 .. it’s new, I’m trying to make sure I hook it up correctly. If it sucks, I’ve got a backup plan is all.

Ok, so rummaging thru some boxes I found a manual for this electronic ignition unit & can confirm that it is a “Hot Spark” brand. There were also a few spare items, including some kind of new ballast resistor block (I think), but no real mention of it in the manual. A little research on Hot Spark found users saying that Hot Spark recommended a resistor.

Anyone know how it gets wired in? I’m thinking maybe between the red wire and the + on the coil? In the pic below you can see that one of the spade terminals on the resistor has a key ring thru it for some reason but there is no indication as to an orientation for installation. Any help?
