There is absolutely no excuse for losing a race due to a poor wiring connection. MSD's Deutsch Connectors are sealed and lock together making them perfect for harsh racing applications. The compact housing of the connectors are moulded from a durable plastic material that will not harden or crack. Each housing is indexed to prevent any chance of mismatching the ends plus they have a moulded channel to secure another connector for a tidy appearance. The terminals grip to the wire with strong crimp tabs then lock into position inside the housing. The connections are protected with thick seals that will keep water, mud and debris away from the contacts. These terminals can handle more current than conventional connectors and do not require special tools. Supplied with terminals, seals and housings.
