Basic question (newbie)

Ok the guy before me re-wired the iginition from the column to the dash with an external switch. It looks like the switch in the column busted and he never fixed it. I plan on changing it I'm just trying to get the motor started and idling for the moment. I'm not wire savy enough to tell you how he did this but he some how bypassed the purple wire all together. I'll test the purple wire when I get to the garage later on tonight to make sure that its dead but almost possitive.

The orange wire with the ignition on is hot. It's on the outer fuse block (inner=under master). My headlights work with the wire not connected to anything and so does everything else.

If I have 12 volts from the orange wire why wouldn't it work? Not argueing with you just curious.

The MSD manual says to run the heavy red and heavy black to the battery. One of my friends (who is a mechanic) said I could put the heavy red to the starter and that would be the equivalant of the pos terminal. Then if I ground out the ground anywhere it would also be the same as the neg terminal. Just wanted to touch base on this one.

Thanks for the help so far guys I appreciate it as always, The orange wire is my new 12 volt source. He tranfered the column jey to a dash and the ignition switch stands alone on the dash.

I have the battery mounted (someone been paying attention ) in the trunk so running wires all the way up wouldn't really be all that cool in my book. If I have to I will though. John I do see what your saying about following MSD istructions but they are talking about ideal situations which i am not in with my wiring.

My thought here is the orange wire (12 vlts) should go to the msd box as its 12 volt source when i turn the key. My distributor is not geting spark so it would make sense, right?

Then I can follow prety much the same set up as the msd diagram.

I thought the orange wire was my heater motor originally but found that one and this wire to my mistake (sorry guys) is not coming out of the fuse block but from through the firewall.

Thanks again for the help I appreciate it. If I can get this wiring/ignition thing figured out I can get my car starting on its own will thanks again.
