After talking out from the fabricator, turns out he can't fit all 6 aftermarket gauges in the place of the older gauge cluster, so the best he can do is 4 or 5. Because of this, I came up with the idea to have a mini shift light (Auto Meter #ATM-5330) mounted IN the custom gauge panel, between the Tachometer & Speedometer. According to the shift light, I have to purchase a RPM-activated switch, but the one offered by Auto Meter is for a Capacitive Discharge ignition (that's a distributor, right?). Well, I'm running a Delteq DIS, so what do I use?? Would this work with the shift light, even though it's MSD?

# MSD-89561

 

If you're still running the stock PCM, you have the Opti feeding it. It will still be producing the RPM signal for the tach.

 

Could I get away with one that has a built-in RPM reader, like this:


It's a little bigger than I wanted, but it's overall a cheaper unit than buying the other shift light AND RPM-activated switch. Are the shift lights that require RPM-activated switches better in terms of accuracy?

Also, when I go to an aftermarket PCM (Megasquirt, Accel DFI, FAST, BigStuff-3), will this shift light setup still work? I'm not really sure on the mechanics of the whole thing...

 

Anyone? Does anyone know whether or not I can run an RPM-activated switch designed for a capacitive discharge system if I plan to continue running the Delteq setup AFTER I eventually upgrade to an aftermarket EMS, like FAST or BigStuff-3???
