24OZ Posted October 8, 2007 Share Posted October 8, 2007 I have MS1 with V3.0 with the Relay Board I am hooking up my turbo CAS Dizzy and I am following Moby's sticky.. I just have a couple of questions I'd be grateful if someone can confirm. Below is the wiring of the dizzy as in Moby's post: Dizzy side ------------ Harness Side Red (12v) B/W White (MS trigger) G/B Green (not used) G/Y Black (gnd) Black Now is the the Red (12V) a key on + or can I directly wire it to the + pole of the battery? Is there a place for it to go on the relay board? I believe the White (MS Trigger) should go to the TACH on the relay board. Also don't quite get where the 1K resistor should be fitted?? The Black (gnd) can just be ground anywhere in the engine bay? Or should that go back to the relay board? I can't see a return for it though. Sorry if my questions seem obvious, I now I am struggling here. Read things over a few times and I know this is not my forte. Thanks folks.

Matt Cramer Posted October 8, 2007 Share Posted October 8, 2007 Red is key-on power. The MS trigger goes to the Tach terminal on the relay board. You can run the 1K resistor between Switched 12V and the Tach terminal. And you can ground the black most anywhere - I'd ground it to a spot next to the relay board ground.

24OZ Posted October 8, 2007 Author Share Posted October 8, 2007 Thanks for the reply. All sensors are wired up now, just leaves me with the coil, dizzy and fuel pump. I'm sure I'll be back pretty soon! Quote Link to comment Share on other sites More sharing options...
