Re: Front-wire harness question
There are two harnesses under the hood. One is the forward lamp harness and the other is the engine harness. The forward lamp harness has ten pins or connections. An indicating light cluster has wires in eight, the bottom two are not used. A full gauge cluster has wires all ten, the bottom two are used for the amp gauge. The engine harness also has ten, seven are used with a light cluster six with full gauges. The blue wire for the oil pressure switch is not used with the gauge cluster.
M&H will supply a direct replacement for the factory harness. If your dash harness is for full gauge and you plan on adding a gauge cluster then you want M&H #05740 (Forward lamp harness, All with gauges), and # 05735 (Engine harness, V8 with gauges). The M&H harnesses are relatively easy to install.
Painless is a complete, bumper to bumper, harness. For about the same amount of money you will spend for the two under hood harnesses you can get a complete Painless harness. The painless harness is more difficult to install.
