Do my dizzy+coil look aftermarket?

[Tucano396]

While checking out the spark plugs on my [still relatively new to me] 94 Suburban, I noticed that some wires coming out of the coil... don't quite seem.... stock?

I dunno, usually there's a neatness/orderliness you see in stock wiring

Given the literal pounds of "let's use a TV coax cable for part of the trailer harness" -style electrical butchery I've already pulled/corrected in this truck, I wouldn't be surprised to find a tacky hackjob here too

Can anybody with an experienced eye pick out any clues from the attached photos? Or does it all look stock? If nothing else, that coil sure looks rusty...

Can't see the distributor itself much at all, seems to have a black / not shiny finish which probably means stock or remanufactured stock unit. Factory cap is black so that's been changed but if your truck has any miles at all, you want to see that. Factory coil is black too I believe so that has also been replaced. So have the plug wires, no big surprise there.

Looks to me like stock replacement parts and an original wire harness that's had its covering removed.

IDK if your 94 was built different but, it looks like the MAP sensor has been moved, at least my 88's is on the same bracket as the EGR solenoid, just on the other side. Probably no biggie. The distributor and coil look OK.

Agreed. Stock, or stock-replacement parts. At least one short section of convoluted tubing has vanished (common) because it gets old, brittle, and basically crumbles. There is nothing wrong with stock or stock-replacment parts. Don't go thinking you need some boutique-brand ignition module, or ignition coil, or whatever. If the OEM parts are working as they're intended, you'll gain little or nothing with the fancy crap; in fact you may go BACKWARDS in reliability with brand-new (Chinese or other bottom-feeder) aftermarket parts.

I hadn't noticed the position of the MAP sensor, just that it had a GM emblem on it. Yeah, mine belongs on the bracket to the passenger side of the throttle body. Perhaps '94s were built differently.

Perhaps '94s were built differently.

They were different, like the EST module was incorporated into the PCM. Maybe the MAP module was moved then too?

Thanks all for the feedback! As time permits i'll pull the cap, see how everything looks condition-wise, and repost if needed

And agreed, I've never been one to fall down the modding rabbit hole. More than once i've been the sorry SOB who owns a car years later once the mods have started to go haywire and are compounding/masking other problems
