My vacation started after work Friday! I'm off for 10 days straight, which means lots of nothingness! And also alot of tinkering with the car. I have a couple projects I could start, install the turbo cam (without a adj timing gear...in an auto), work on my 3 inch exhaust, I have almost everything needed for the electric fan conversion, but to stay cheap, I chose the wasted spark setup. I have everything BUT a mounting plate. (There slacking next door) so for the time being I will use some heavy duty zip ties to secure it to the strut brace. They say rated up to 150lbs tensile strength, hopefully 6 will be good enough...
Since it was fathers day Sunday, the family and I went over to my brothers to grill out and let the kids play. While over there, I pulled my ezk out and we got to work.
I chose 20 gauge wire, but if I were to do it again I would use 22. Just makes soldering onto the tiny points easier.

Working along...

My brother had some 4 prong male and female plugs that work very well for this setup, so drilling the ezk box to fit it.

So the days coming to an end, we enlarged my brothers air filter shield to fit his 3" AMM, and I'm throwing my now wasted spark ezk back in and hopefully drive away with no problems. Running on the stock coil and distributer of course.
Well nope. It cranked, but would not fire. So I put in a spare black box ezk and drove home. Broke open the gold box to find out me and my brother rushed and put the 5v onto the wrong pin, so a quick fix and went to test. Fired right up, awesome. Now a lot more work to do.
Took the box back out and hot glued everything in place so nothing funny happens in the future.

Now onto the engine bay. I ran the wires out the cab and to the left fender where the stock ignition module is. Covering the long runs of wires with some plastic tubing, solder, heatshrink, and in some spots I threw a layer or two of electrical tape to be sure. Wires go from the fender along the strut brace and to the coil.

I just put the j702 module where the stock one was, with some new thermal paste, the plan, as is everybody's I assume, is to use the j702 for the tach, since it has its own spot. Well mine didnt work. The red/white wires from the original module didnt work for me. So connecting the old module back up and leaving it hanging will provide my tachometer.

I guess I got a dud from the jy?
Id say looks pretty clean for my standards...cant wait to get the mounting plate on.
Oh yeah, a new set of plug wires since all of mine broke coming out the distributor

Now its all finalized I go to test drive. (I definitely wired it up and started it before soldering/heatshrink) but since I had to keep my stock module for my tach, I used the power from my resistor pack bypass to power my new module. I dont think the injectors liked that very much. My afrs were going 10 to 16 while cruising and car felt like it was missing on load. So I stole power from my coil..well the red/white wire works for power, but if its not connected to my old coil then the tach wont work...
For now my power is coming from the old coil. But when I want to rid the car of the coil, where should I get power from and still be able to keep my tach?
But after that, I drove 10 miles, car feels nice, afrs are solid like they were with the stock ignition system in. The occasional miss/rich spike at cruise is still there. I guess the ignition system is crossed out at the least. But now, wasted spark!
