3B732F77-A7F7-4D0B-92B2-BAE7470ED5C3.jpegI’ve had the Gen4 combo package for a while now, just never got around to installing it. So far I 3D printed a mount for the gauge which is a ring that goes around my boost gauge with a cup that holds the PLX gauge. Wired an ATO 5A fuse to one of the two open IGN sockets on the fuse panel. Grounded the negative to the ECM B9 using new pin, came out great. The Ipiss... I mean IWiss crimper from Amazon worked perfect, same with the new pins from EBay. Super easy. Last, I crimped a pin on the wideband wire and installed it to F14. No capacitors needed for Gen4 units.

For that I need to remove the passenger fender and fish the PLX plug end under the heater core where there’s a hole. I don’t expect any probs removing the old O2 because I always use antiseize. I’ll update here when I get around to it, but so far so good. (y)

4E4095D9-E91A-4EA4-BBED-ED796A3C8BE3.jpegIt’s done. Pinned the narrowband wire. Swapped O2s. Ran the O2 wire under the heater core through the access hole. Plugged it all together and closed shop. Drove it to Target and Chipotlé. Smoooooth. I also installed a Powemaster 140A Alternator. Everything is working perfect so far.
