If I need a relay board for my 75 can I use one from a earlier car? Just want to make sure the main chassis harness plug will fit a earlier board. This will be going into a six conversion.

All the /4 boards are the same. The Cap'n

914/6 part# is 914 610 103 00 914/4 Part#914610 104 00
Different part# for the 6 and the 4. All 4s seem to be universal.
