| | Mercury Outboard EFI TPS Test Harness
OEM Mercury Outboard EFI test harness. Checks throttle position sensor setting which effects air-fuel ratio. OEM connectors easily plug in and allows a simple votage check. I used these to correct an over rich / rough idle condition on my 98 2.5L 200HP. $20 Shipped lower 48.
