How many wires go to it. I have a 60 amp Denso on my car and it is internally regulated. Three wires. One to battery for charging, one for voltage sense, and one for a charge light.

74 Challenger, bought it new. In 1978 I replaced the original 318 with a 446 and 727. Mild cam, Jardine headers, and Holley Sniper EFI.
New engine! 511" RB, Edelbrock Performer RPM heads, Eagle rotating assy, Comp hyd roller cam, Doug's 2" headers.
