LOL thanks really OLD pic.

i think ive had this before. if i remember it needs a ground line, a power source and an actual signal and the last wire is the output which i think is grey?

the signal is the 12v line going to the coil... i cant remember which line it is and you should meter it (dont use a test like you migh blow out the coil) but i think its the middle line but im like 70% sure thats the one...

if you want give me your year and il look it up in ALLDATA for you because if i remember the coil lines changed like 2 times while the 2gn's were in production

DG/OR is the supply
BK/GY is coil #1 (cyl 1+3)
DB/TN is coil #2 (cyl 2+4)

the wire your looking for is the DG/OR wire, the tach adaptor reads the current draw from the coil and comes up with the RPM.

there is a howto on how to install a magnum manifold that uses a tach driver to get the RPM's to help open and close the secondaries you might want to cross reference that but im sure that driver is looking for draw and not the digital signal going to the coil from the PCM

PS if none of these colors look familiar... look at your injectors, all 4 of them should have one wire in common, that same wire is the supply line on the coil
