I apologize for the lack of updates. I'm finding that the COVID19 pandemic, among other things going on, has slowed my motivation and progress lately. My family and I are hunkered down at home, I'm working from home full time, and my dad had been in the hospital for several weeks. Sadly, last Wednesday, my dad passed away.....so I'm dealing with that.
Anyways...here are some of the things I've been working on lately:
I finished gutting the Samurai wiring harness and sizing the ABA harness, so the next order of operation was to make a relay/fuse panel. It is nothing more than a piece of aluminum angle mounted to the body. It will utilize two relays, one for key on power and one for the fuel pump/engine electronics. I sourced these from Parts Express along with the dual socket for them:

There are also a couple of fuses that I had to add into this harness as well, so I sourced this on ebay:

As I mentioned earlier, the stock Samurai harness has been gutted and wrapped with friction tape. Luckily I purchased the tape at Walmart just before the COVID19 craziness went down. I'm glad I bought two rolls, cause there's no way in hell I'd go there present day if I needed to get some more:
This is the new relay to ABA harness interface:
And the relays/fuses all wired up....pre-wrapped:
Post-wrapped:
It all unplugs very easily, in case I need to swap out a component or troubleshoot:
After this was all finished, I checked everything to verify that it was wired correctly. I scanned the ECU with VAG-COM, ran output tests, etc, and everything appears to be in order. :thumbup:
My stir crazy, home bound kids were driving my wife bonkers one day, so I let them inside the garage to take their aggressions out on the Samurai interior:
I was at the stage where I needed to remove the remainder of the stock ECU harness, remove the AC portion of the HVAC box, and also mount the fuel pump. In order to do all of this, I had to gain access to the passenger side of the vehicle, which was up against the wall. With a series of Austin Powers style 30-point turns, I was able to finagle it around the garage under manual power and get it in the position it needed to be in:
Up first was to remove the remnants of the Samurai ECU and the AC harnesses:
AC module on the left, ECU on the right:
Then I removed the AC box, which came out pretty easy. Surprisingly, it did not require dash removal:
So much more space under there now!
All buttoned up:
This is everything AC related, that was removed. Sadly, the parcel shelf on the passenger side was cut at the dealership to make room for the AC box, so I will have to track a new one down that hasn't been bastardized:
I received a package from Performance MRP, as well:
The package contents:
I contacted Matthew at
https://performancemrp.com/ to see if he could add a 3/4" diameter port to one of their standard MAF housings
https://performancemrp.com/i-30497582-volkswagen-mk3-mass-air-flow-housing-with-air-straightener.html?ref=category:1389188 for me, so I could incorporate the ABA PCV system to my intake. This was something he was happy to do and he pulled it off beautifully. The port was placed exactly were I needed it and TIG welded on. The machining, the welds, and the overall finish were absolutely top notch, I couldn't be happier. I'd highly recommend them for any of your MAF housings, block off plates, intake flanges, or general fabrication parts needs, no question.
Close ups of the modified MAF housing:
And some pics of the test fitting. As you can see, the part fits great and looks even better. The finish is super nice, as is, so I'm on the fence as to whether I should paint it black or not:
That's not it from Performance MRP, either. If you noticed in the unboxing pic, there is another "little" part that I mentioned prior to this post. It has arrived, it's also beautiful, and I will go into details on what it is in the near future.
The whole COVID19 thing really makes picking up a random nut or bolt or whatever you come across during a project difficult. I don't want to venture out frequently and potentially catch it and bring it home to my family for a $.30 hex nut every time I need one, so I find that this is slowing me down considerably. I miss the days when I could go into my local hardware store and aimlessly walk the aisles in search of a solution to a problem. As this project comes to a close, I find this is needed more now than ever. Today I placed my first "Curbside" pick up at NAPA, for fuel line, fuel hose, and a line bender.....we'll see how that all goes when I pick it up in a couple of hours.
So that's it for today's update. Hopefully now that my life got less stressful, due to my father's passing, I can focus and get into this project a little bit more than I have been able to lately. Up next is fuel pump/filter mounting, running fuel lines, and ultimately firing this baby up.
