Question about the wiring side of a 3B swap. My plan is to combine all of the non ECU components from the 7A harness with the ECU components of the 3B harness. I've got the ECU pinout diagrams for both the 3B and 7A, but does anyone have a diagram or list of all the other things that are on the main wiring loom?

Thought it would be helpful to know what's what before I start integrating the two. I do have the bentleys to fall back on.

DAMN! is that really rust!! :eek: :eek:

I saw the picture on facebook and thought it was what was left of the underlay/under carpet stuff. Out of the 50+ cars i've had I have yet to see any of this year/model coupe's with that much rust.

Where was the car from originally? I wonder if the matrix had gone and water sat in the footwell?

Hopefully it is just surface rust, if so that will be easier to sort.

Yeah, that picture on Facebook was before I removed the carpet pad. I've always had a suspicion there was a water issue, based on some rust around the floor mat pegs. But I was shocked to see how widespread it is. Seems to be limited to the driver's side footwell. The heater duct that runs to the rear footwell has a rust colored water mark on it. I'd estimated it had an inch or two sitting for a while.

Car is from Milwaukee, but has little to no rust on it externally. Most I've seen has been on the rear subframe.

I plan to hit it with a flapper disk to see if I can get to some good metal. If it is all the way through, would it be best to make my own floor pan and weld it in?

Holy crap! I thought mine was rough! I would scrape it, wire wheel it, then use a good converter and paint on it. As long as it's not through, you should be fine.

Agree, hopefully its just surface rust.

Good luck with it, I found some rust on my white cq and ended up switching to a black 7a turbo cq instead but even that needs work :frustrated:

I've come this far with this car, not gonna let this stop me.

I had very little time today to work in the garage, but I did manage to hit a small spot of the floor pan with a 60 grit flapper disk. I need to get some wire wheels for my grinder. With just some light grinding, bare metal started to peak through. Granted, this was a higher spot, but hopefully the rest will clean up.

I do know of at least one hole. It presented itself while just scraping off the flaky stuff. Weird thing is the underbody coating looks perfect from underneath, even where the hole is.

Hmm strange, at least looking at that it looks like some reasonable metal under the surface.

Whats your plans for the running gear once done? full s2 rep 5 stud?

Probably not the most popular choice, but I am sticking with stock brakes. Maybe I'll do the 5 lug and bigger brakes down the road. A lot people do it for more wheel choices, but I like the TSWs a lot.

Yeah I'm going 5 stud on mine as I have a few sets of rims that are 5 stud. If you do go five stud and want to get rid of the tsw's let me know.

Like I said on the other site, please use a wire wheel in a drill. If you've seen my coupe thread, than you've seen the damage you can do even with that. I went from a dime sized hole, to Swiss cheese with a little scraping and a wire wheel in a drill.

Also, you can out me in the list for those wheels too haha

Glad to hear other like the TSWs as much as I do.

Thanks everyone for the advice. This is new to me, so you won't insult me at all by offering even the most basic of tips.

Considering that I would be applying a rust correction product like POR15, am I looking to just knock down the high spots?

Definitely don't want to remove any metal, just the loose stuff. You'll want to pick your wire wheel wisely, and not get one that is super stiff.

Spent some time trying to clear out the wiring harnesses that run along the door sills.



This is what scares me the most about all this mess. This is the bundle going to the driver's seat. It's a wonder it all worked.

I have wrapped all of the wire bundles in new cloth tap and I'm crossing my fingers that I have not disturbed them too much. I have not seen any sections where the wire insulation has flaked off.

Last weekend I managed to scrape all of the original sound proofing material off. Driver's side rear floor had more rust than I thought it would, but not nearly as bad as the front. I also was able to remove the sticky residue left behind in the areas where the metal was in good shape, but failed to snap a pic afterwards.

Next up is to find all the holes and thin spots and start prepping for POR15. I plan to use a combo of mesh and several coats of POR15 on those areas. I think I am going to coat the entire area under the carpets in it. It'll be black, but it's all covered up by carpet and trim.

I'm sure i've seen some paint on products that will kill the rust that you can paint over with por15. Would be worth giving it a go over with that stuff then por15 it before doing new under carpet material.

I do plan on using the POR15 metal prep that etches the metal and leaves a zinc phosphate coating behind for the POR15 to adhere to.

Anyone have a recommendation on what to use for jute between the carpet and sound deadening material (I plan to use KilMat)?

Can you share a link to your coupe thread? TIA
