Wiring, wiring, wiring. I'm making progress I swear.



I bought a spare used 14-pin 944 connector. This is the plug in the engine bay that sends signals to the oil pressure and coolant temperature guage. I'm also pulling a few switched 12V connections off here. There's also a pin here that sends 12V directly to the fuel pump, so I'll be taking advantage of that too.



It looks worse, but it's getting there. Long red wires are going to run to the fans, waiting on some wire sleeving before I route those nicely. White wire will go to battery and sends power to auxiliary fuse/relay bracket under dash. Other loose wires go to 14-pin connector.



Finalized all the connections under here to the auxiliary relay/fuse panel, just need to remount it and tuck and zip tie wires. The blue wire attaches to the plug with the little piece of tape on it in the centre of the picture, that's the tach signal.

Making plug wires, running plug wires. I used MSD kit 31193 and substituted the MSD 3304 LS1 coil ends for the ones that came in the kit.

Did a little "while you are in there" maintenance last night. My fuel pump died a couple years ago and I replaced it, so that is still fine, but I've never changed the in-tank fuel screen since owning the car so I decided to do that while the tank was dry.

I also dropped the fuel pump to change the delivery fitting to -06 from metric in preparation for setting up the lines to run the Corvette style fuel filter/regulator which will replace the factory filter.

Started roughing out my intake situation. Built a little bracket to hold the intake pipe forward and up from the power steering pulley, there were 2 existing studs there I could make use of to secure the bracket. Please excuse the lack of hose clamps and filthy filter, the whole setup was in and out multiple times for fitting and the filter is just for testing space, I need to grab a new one.

Still some work to do, need to drill the pipe to place the AIT sensor and the hose barb for the PCV fresh air source.

So close!

Can't tell from the photo but how is the intake tube fastened to that triangle bracket on the tube side? Is it a captive nut on outside of tube?

There is a hole in the tube with a rubber grommet, a bolt passes through the grommet from inside the tube then through the triangle bracket and the nut goes on the end of the bolt. The tube is big enough I can reach inside with a wrench to back hold the end of the bolt while I tighten the nut.

Yep! Totally agree. But you're making consistent measurable progress and that's the key.

That's terrifying. Are you using loctite on the bolt/nut combo? I have this extreme irrational fear of metal objects that can rattle loose in my intake. I understand by the looks of the photo gravity should keep it from any extreme trips in the wrong direction but I'd be worrying about it all the time regardless.

That's a good irrational fear to have Matt! It took me 20 minutes to work the bolt through the rubber bung it's such a tight fit. I'm not convinced I could get it out if I wanted to. The nut outside the pipe will get some loctite to make sure it stays on.

Could always drill the shank of the bolt and add a little cotter pin for extra extra extra safety
