I am currently trying to install a Tach, and have no clue which wire to connect the RPM (green) wire to on the distributor. I dont have the manual, but will get it as a last resort.
Thanks for the help.

 In the pic you see two caps if the timing is pretty good it will sit close to this way, looking from the drivers side. The cap cover should say Tach on the left side of cover. The two closes to the out side corners because the dist plug with three wires goes closes to the HEI cap . That where the Green wire from the tach goes on the coil, Red to key on power at the fuse box, White to dash lights/ White wire under dash, Black to body a good "Ground"!. This is a after market tach most 1980's-up.
for the factory tach's you should see the wiring for your year truck because not all years factory tach wire the same they hook up a little bit different |
