I am installing a MSII-V3.0 with ignition control. I am running a GM 8-pin HEI module in a small cap, external coil distributor.
I am in the process of terminating my DIY AutoTune harness and I am confused by the shielded twisted pair of wires indicated to be coming from pin #24 of the DB37 (http://www.DIYAutoTune.com/images/mshar ... wiring.png), and it's connection to the 8-pin HEI module. Will one of the twisted pair of wires connect to pin "R" on the module, and the other to pin "G" to ground the module? Will I only use one of the twisted pair of wires to go from pin "R" on the module to pin #24 on the DB37, not use the other, and run my sensor ground to pin "G" on the 8-pin module?
The "GM HEI" section of the MegaManual gives an idea of how to wire up the 8-pin module, but does not address the shielded pair of wires (DIY AutoTune harness specific?) or where to ground the module (I would assume with the rest of the sensors would be best?).
I've searched these forums, the DIY AutoTune site, the MegaManual, and Google for hours trying to nail this down. Hopefully I haven't missed it somewhere. Thanks in advance for your help!

Re: GM 8-Pin HEI & Shielded Twisted Pair
Nevermind. Upon further inspection the wire is labeled "WHITE: CKP+" and "BLACK: CKP-". I also pulled the cover off the DB37 to confirm. I'll connect the white to the "R" pin and the black to the "G" pin on the module.
Sorry for the dumb question!
