Lower Plug Wiring.
Purchased 6 more AUDI COPs from a Audi/ VW on-line retailer in Washington State. Way… Much... Cheaper than the first 6 I bought in that Adapt Motorsports bundle of goodies. Had to source the harness connector kit (enough for 8 coils) on eBay so I now have a few extra pieces on hand so that’s a small plus.
Needed 12 NGK plugs as well. I think someone on the ECU Master Black community forum recommended this plug number as a suitable shorter length plug with a heat range sufficient for this air-cooled motor. We shall see. NGK BKR7E-4644. They are a tad shorter and now my COP’s in top valve covers fit more flush so I love that!
Time to wire up the lower Coils. So, first thing first – locate an appropriate spot to splice into the 6 existing sequential ECM coil trigger wires. Others had confirmed that the ECU Master Black could handle both upper and lower coils on the same wire. Worked for me – proceeded with little caution, lol ! Splices are down lower at the backside of firewall. Everything was carefully crimped, tested, heat-shrinked, wrapped, etc to prevent issues. Power wires and a fresh ground wire on RH and LH side of transmission/ engine bolts provided good grounds thru the Deutsch DT single LH and RH connectors.
I have developed a passion for building harnesses. Making good crimps is satisfying to the soul. Cannot explain as I’ve just developed this skill in past 12 months. I love it.
3:1 Heat shrink does a nice job as you can bend it into desired shape as you run your heat gun back and forth.
