I bought a LS1 crate long block and it came with "coil harness*". Notice the "*", the coil harness came in 10 individual bags (kit form I guess), with white wires coming out of each connector. I have searched and found the wiring diagrams that talk about color of wire and what they do. The diagrams are labeled with Letters for the pins, but I have not found anything to show which letters correspond with which pin on the coil or main connector.

I am told the motor came with old style coils, connector and spark plug wire are on the same side of the coil, if that makes a difference.

Thanks

PS. Carb because I want to and thank you to everyone that post here. All your questions, answers and opinions are priceless for all the projects like mine. Not sure I would have tackled this with out this site.

I would just be lazy and find some harnesses somewhere that I could throw on there for next to nothing. That is weird. Someone here MIGHT have some input, but I have yet to hear of that, so pretty lazy on the sellers part I think.

Thanks for the kind words btw, makes me feel like I did a great thing getting this section established here.

Thanks for the reply. I did purchase a coil harness for an LS1 (and others LSx) off of e-bay. This is is when I learned that the old style coils have a Keyed connected and the harness I purchased was for top connector coils with out a keyed connector. I thought about putting the new ends on the old harness, but are the coils (old vs new style) pinned the same??

I think you have stock ls1 coils? There are 4 different coil types off the top of my head, you need to simply find the right harness if you do not want to make that pieced set work. Looks like a headache to me.

Your coils look to be more like truck coils. I think I have a set of coil harnesses that will fit those. I'll trade my harness for what you have if you pay freight for both.

I am ok with what I have, they all work, lol.

I would shop for some factory harnesses if I was you.

My post was for the OP, in case he didn't want to mess with building a setup. After looking a little closer at his coils, their not truck coils anyway.

LS1MCSS: Thank you for a great offer! A couple days ago I would have jumped at it. I was able to find some information at:

A little over half way down this page, they talked about the pin out for this coil. Using the wiring diagram I found on this forum and my MSD 6010 installation instructions, I think I have it figured out. As you can see in the pic below I have not done anything permanent. If or should I say when it starts and runs, I will take this apart, shorten the wires and lay them out nice. Would like to run them under the coil mounting plate.

It will be a while before I get to find out, have to finish the steering, fuel system, accessorie............. you know what I mean. When I get everything to work I will document it here in case someone else ever needs the information ooorrrrrrrr I will be PMing LS1MCSS to see if he still has spare harness

After getting a better look at your coils, I can see that they are LS1 coils and my harness is for truck coils. It won't fit yours.
