77. I decided to go ahead and wire in my J&S Safeguard, although it is set to just monitor at this point. Once the tune is more dialed in, I will turn it on for added protection. I studied the Spyder wiring diagrams and chose what I thought were the best power and ground pins for the J&S. Everything else is pretty straight forward. To help me keep all the green wires of my patch harness straight, I picked up a label maker and labeled all the wires I’d be cutting. I also didn’t want to use the wire taps, because these wires are pretty thin and taps can weaken them plus not give very good continuity. So I soldered all the splices, then covered them with heat shrink.

78. To keep everything neat and strong, I zip tired all the wires together, which also kept the labels out of the way. The long thin white wire is coming from the J&S and will run to the Datalogit so I can log the degrees of retard that the J&S is adjusting.

79. Installed back in the car. You can see the thin white wire run to the Datalogit, in addition to the LC-1 WBO2 and boost/vac sender. The J&S is velcro’d down and I have enough slack in the wire that I can remove it and place it next to me while driving to fine tune the sensitivity. It’ll go back under the cubby floor once it is all dialed in.
