HEI DUI Distributor Wiring

[BusaDave9]

a 30 or 40 amp relay will work fine. These are common. They are often used for off-road lights.

​

These will have 4 or 5 connections. Either will work. The terminals will be labeled 30, 85, 86, 87. (Do NOT ask me how they came up with this numbering scheme). If there is a 5th terminal it will be labeled 87A but you don't need to use it. (as an FYI the one with 5 terminals is a DPDT and 4 terminals is a SPDT) These numbers on the relay match up with the drawing above.

Hella makes a great weather proof relay with locking connector with 12" pigtail wires. I shopped around and found the cheapest price from www.genosgarage.com Complete unit for $15.00. Look under the electrical section on the online catalog.
