I am now thinking of hooking the Tach up myself, but don't know how to wire it correctly.
Any help will be appreciated.

You will need a way to identify them. One goes to the hot side of the ign switch when you turn the key on. You can hook it up at the fuse box. One goes to the neg. side of the coil or the Tach. term. on HEI. One goes to the dash lights (usually grey). One is grounded (usually black).
They say money can't buy happiness. It can buy old Chevy trucks though.
