Bruiser Conversions’ V8 engine kit for the Jeep Wrangler (and Gladiator) integrates both Chrysler and GM components to create a single, seamless, high-performance system. Bruiser has engineered a system to connect all the factory Chrysler components with specific GM components allowing them to communicate through the Chrysler PCM (no parasitic GM controller used) and the one factory OBD2 port. There are no micro switches in the tap shifter, the cruiser control works, and all the gauges function with no dash lights!
