First off you need a Rally gauge cluster with the original circuit board in tact. You need to swap the #5(tan) wire and the #7 brown wire at the back of the guages. On 68's, you must also cut 1 wire and I forget which one. That's it.
p.s. Green wire goes to temp sender, dark blue goes to oil sender.
