Made a little progress this weekend.
First I took out my dash to deal with my 'leaky' heater core. Took it apart and checked to make sure it was really the problem.

If this b!tch was going back in my car she'd have to hold it together underwater.

Turns out she could. Held ~ 45psi for over 3 hrs while I worked on other things. I pumped it up, sealed it, then put it underwater the whole time with an in-line modified compression gauge (removed schrader valve) to monitor it. I guess my leaks must have come from around the inlet and outlet pipes. Doh!
I also returned my optima battery this weekend. After spending 7 months in the shop, and deep cycling despite me telling the guys to keep it on its trickle charger, I couldn't get it to hold charge even with the parallel charger + good battery trick. Thankfully I bought it locally and O'Reillys didn't give me any trouble.
While I had my battery out I decided to go ahead any install the mil spec bulkhead connector I'd bought to make my wideband sensor install / uninstall easier for open air calibrations:





I also went ahead and coated the top of my battery holder with Plasti Dip because I just about sh!t a brick every time I work around it because I'm afraid the terminal clamps may accidentally touch the plate and short out. The plasti dip is rougher than I'd like, but it's a good insulator and supposedly it peels off if I end up not liking it:

Also started installing my AAC aftermarket carpet. It's been in my attic for over a year but it still makes my car smell brand new + It's SOFT! I can't tell you how many cuts and deep punctures I've got from working inside the freakin cage of a cabin with so much exposed / sharp metal edges. I'm so glad to have a little padding again




This was my method for marking my holes to be cut with chalk:

Here's the install at ~ 80 % complete. I'd cut all the holes at this point and was installing padding. I still haven't trimmed the perimeter though:


Sorry. I didn't get any more shots, but they'll be coming when I finish.
After I got the carpet mostly in I started second guessing some of my electronics since getting the carpet in makes changes significantly harder, so I started verifying my alarm setup. Up till this point I haven't worked on my door locks because my doors have been disconnected. Well I got them hooked up and was astonished to find that the stock door lock system only used a solenoid in the passenger side door

I even missed it with the diagram shouting in my face the whole time. Oh well, I've got a solenoid on order and I'll get it fixed up, but it's a pita to have to work on the alarm wiring at this stage.
