MSD Solid State Relay

This is a great relay at a heavily discounted price. We used it to trigger our Transbrake, Methanol Interrupt Switch, Two Step, Boost Launch Feature, etc. One of the input screws is a little loose, but there are several work arounds to make a firm connection, or you could just completely bypass the one input that has the loose screw. Choice is completely yours.
