Anyone have a source? I am putting GM coils in my 94 NA8. Using the 585s with a stock harness. I would like to cut off the connector on the GM harness and then tie it into two female connectors I plug straight into the stock male plugs that used to go into the factory coils. Also can someone spoon food me exactly where the damn tach out from the Rev MS3 needs to go. I understand that I need to run DB 10 to something but in all the searches it isn't clear to me where.

 

Why not do the opposite and use the GM side to plug into the GM harness?

 

I cut the connector off with a saw and trimmed back the plastic to expose the leads to solder onto on my CAS. Can't see why the same can't be done with the coils. If you can't find connectors of course.

 

For GM/Delphi metripack 8 way (1 blocked) connector used on the ignition harness you can get them below

Female pigtail:

or just buy one of these and cut the end off (be careful, wiring color may not match one harness to the next)

You're welcome.

 

You can repin the harness side to a pin-compatible plug of the same type (2x2 square Sumitomo DL) if sliding out pins feels less bad than cutting. Putting GM connectors on the harness is definitely the easiest and cheapest way, though.

Both genders are available for the 2x2 sub-variant. Unless there's been a recent change, the 1x4 mate isn't.

 

Those plugs are nonexistant. People have long been searching for them.

 

Makes sense on why I couldn't find them.

​​​​​​​I am going to go this route. I am going to cut the connector off my stock harness and patch it into this. I don't see any reason to bother changing it from wasted spark right now. I still don't get where to run the tach out wire to. And I thank you.

 

Eat my *** whoever neg catted me for this. MY TACH WORKS!! I don't know why though. I didn't run anything to anything and my B/W are cut at the coil so I am guessing Rev has something done internally for it to work. WINNING. MS Labs for the win. Seriously.

 

You don't drive a 1.6, that's why your tach works without doing anything.

 

In all my reading I never read that. Everything I read mentioned a tach issue. The more you know.
