    That totally depends on where you plan to mount the transducer You might want to get a relay, along with a fuse holder for the electrical part of it

    I installed a relay to power additional electronics when the key is plugged in. The relay basically uses a signal wire from the MPEM, and the power to provide the gauges comes from the battery... not MPEM power.

    i have the instructions at the shop it was working ..but when we first went out it was flashing 7.5 ..i am thinking that is the warm up cycle...when you first start it the o2 guage ..is heated it was really cold out...so wondering if that is all it was ..it just took a bit to get hot enough to work...then it was working just fine
