Hooking up an inline fuel pump to a distributor doesn't make much sense. What is it you're trying to accomplish?

If you're trying to make the fuel pump turn on when the engine starts, use a relay and the fuel pump control wire that the ECU currently uses to turn on/off the stock fuel pump.

Then yeah, just use the ECU's fuel pump control wire to turn a relay on, which in turn applies voltage to your fuel pump. If you're asking how to actually hook up a relay, How Stuff Works has a great little write-up.

Tap off of the wire for the main relay and run it to another relay and then to the inline pump.. I think its wire #7 on the main relay harness..

I wouldnt use the dizzy but if you really want to, its the thick wire that is on the 2 plug harness.. DONT POWER THE PUMP FROM THAT WIRE, just use it to switch a relay..
