suntach, msd 6al and tach adapter

[Brightyellow69rtse]

ok i got a suntach and a msd tach adapter. can someone tell me how to hook up the wires on the adapter?   the adapter has a violet,red,white,black.

the tach has green which is the signal wire according to the instructions, black which is ground, red is hot and white is lamp.

i got all new harnesses and i have yet to cut into them and would love to avoid this or use as few splices as possible. thanks

i think i got it all figured out as to what goes to where. but whats the easiest way i can tap into the ignition wiring?

i got it all wired in only thing i noticed was idle dosent really register at all.  i put the 3k rev limiter chip in and it was cutting out around 2800.  so either the tach is a bit off or the chip is.
