Tell me if this is right?

After doing the switch over to HEI and cutting the original wiring, is there only one wire that now runs to the starter? I trimmed of the yellow that went to old distributor and am left with one purple that goes to starter. I know a red one goes from distributor into fuse panel. Where in the fuse panel does this wire go? Getting ready to start truck soon and work in the new cam, headers, intake and carb. Regarding cooling, I have a 454 motor and a new 4 core rad. Will a normal steel blade fan do the job cooling wise? Should I use a 70's style fan or a clutch type fan? Thanks for any help.

Yes, you will only have 1 purple wire to the solenoid. the yellow wire gave full battery voltage to the coil while the starter was cranking,then the point system ran off the resistor wire(approx9 volts). I have a 10 guage wire from my HEI , to IGN unfused in the fuse box. Some guys also opt to run an inline fuse in the feed wire to the distributor. on the fan.......I never have liked clutch fans, & am setting my longhorn up with dual electric fans. I have run a Flex a lite plastic flex fan on the larger V8's with good results.......just be carefull with a flex fan(dont buzz the throttle while standing over the eng). I have not had a fan blow .......but have heard the stories,& havea lot of respect for them! good luck.....crazyAL

If you check the factory wiring for the hei, you will find they used 14 gauge. I ran 12 gauge to the unfused ignition port on the fuse block with a 20 amp fuse in the line. I used the wire that went to the coil to power my electric choke (without the resistor).
