Oh, OK! My dad used to have one of those, I'll see if he still has one or at least access to one.

Finally the issue I have been dealing with since before DGRR has been resolved and the car is running now and did so for more than one day! The issue was with the trigger sensor connector polarity.

After receiving the harness I got all the wiring back the way I like it, again. A little more tuning and the car should be a reliable driver. Got her all cleaned up this week and ready for the next joy ride Just have to pass emissions to renew my registration and I'll be able to drive it anywhere.

Congrats!

Did you find this with the O-scope, and was the trigger sensor wiring leads just reversed (+/-)?

No, I couldn't find a grandpa local that had one of these prehistoric machines LOL Yeah, the wires were reversed.

Also, I didn't find this. . . I had no idea what else to inspect and I would have never suspected anything like this to be incorrect so I sent it back to be looked over/repaired.

Zach took the time to pull the harness I had built for him out of the car and ship it back. The root issue was my bad ASSumption that connectors from two different manufacturers would be labeled the same. They weren't. So the two trigger wires on the VR sensor were revered. So after all of the hair pulling the screw up caused Zach, it was a 15 second fix. Lesson learned and hopefully a mistake I won't repeat.

Yes sir, that would be nice. Ideally I would like to have more tuning done before driving outside of town. That, and most importantly my tags are expired so I'd like to have a fighting chance at emissions testing before I waste the time and money. I'll get with Jacob sometime.

Chris helped me out tremendously with making my two gauges (pressure & temp) perform two different functions a piece by drawing up a color-coded wiring diagram as well as suggesting which switches to use. I had been putting this off because I was afraid to cut up the gauge harnesses without being completely sure where each wire goes.

Thursday I started trimming the gauge harnesses and adding connectors and switches to both. I got it completed yesterday, everything worked perfectly. I added small labels to the mount to use as a cheat-sheet till it's commited to memory.


I'm using the temp gauge for oil and water. Problem with using it to monitor coolant temps was that the ECU had its own dedicated sensor for coolant temp so an additional hole needed to be added for the gauge. . . I used one of the coolant bypass ports for the extra sensor by drilling and tapping NPT threads. I've heard plugging the bypass ports is a no no but these ports have been inactive forever without any problems (that i'm aware of. .)


The pressure gauge I'm using for both oil and fuel. No issue here other than the need for a pedestal to mount the two extra sensors for monitoring the oil. I decided to use the FFE 13B REW pedestal that will work on a 13B when the REW's oil cooler hole is plugged, I found the plug on eBay for ~$5 (not pictured).
