ttodhunter Posted August 29, 2012 Share Posted August 29, 2012 Hi everybody, I'm installing some headers for a couple of reasons. 1) There was a massive exhaust leak in the stock manifold that made it unbearable to drive for long distances, and 2) I wanted to put in an oxygen sensor as I will be installing an SDS and need it for tuning. (3- I always wanted headers). In wiring up the oxygen sensor and Split Second ARM-1 for monitoring, I need a switched source for power to supply the heat source for the 4 wire and the power source for the ARM-1. Does anyone have any recommendations for the source of the switched (accessory or engine running) power I can tap into? Thanks in advance.

Leon Posted August 29, 2012 Share Posted August 29, 2012 I suppose it would depend on the car. From your avatar, I'm guessing you have a 280Z? Download the FSM from xenons30.com and trace the appropriate wiring diagram from the ignition switch and find one that you feel is suitable. That's what I did to power the secondary fuse box in my Z. I used the neutral safety switch (which had already been bypassed) wiring in my early 260Z. Quote Link to comment Share on other sites More sharing options...
ttodhunter Posted August 29, 2012 Author Share Posted August 29, 2012 Yeah, woops. 76 280z, manual tranny. I was thinking about the + wire to the coil, or I saw Tony had it hooked up to his fuel pump relay. I looked through the fsm and there doesn't appear to be many fused acc switched wires in the engine bay. Forgive any grammar, sending from my phone.
