After several intermittent electrical problems I began having the relay boards soldered. All connections on the bottom of the board were originally swedged. This is a fairly rare occurrence but to completely eliminate the possibility of stalling, charging problems, reverse lights and other electrics that pass thru this board. Easy to install and works with all 914/4 cars. $299. shipped.

This is the last relay board you will ever need

Skip the core, $299. shipped.

I have these in stock.
