MS2-extra V3.0 board - Chevy 350 TBI from carb with IAC control - HEI 8pin distributor
DiyAutoTune wiring harness
I am using this:http://www.megamanual.com/ms2/V3assemble.htm#ew
at the section "External Wiring with a V3.0 Main Board"
as my wiring diagram ( I saw no "extra" specific diagrams)
Looking at this page for reference:http://www.msextra.com/doc/ms2extra/MS2 ... htm#wiring
at the section "Wiring the HEI module:"
I see that the ground pin is missing in the diagram. It states above it that that the "G" pin is for a ground. Is that just a standard ground to the engine block, or is that tied to the sensor ground pin #19?
The reason I ask is because of this article:http://www.diyautotune.com/tech_article ... 2-nova.htm
at the section "How do I wire it up?"
shows the "G" pin going to the TPS return. The diagram above shows that TPS return is going to the sensor ground?
To confuse things further for me,
at the diagram"HEI 7 pin wiring diagram"
shows "G" going to pin #26 not #6 as stated in (http://www.msextra.com/doc/ms2extra/MS2 ... htm#wiring
and also shows using a relay?
