Hi, I'm new to this forum and also new to boat ownership. I just purchased a bass boat hull only, no motor. Boat is a 1998 Triton that had a 175 Johnson. I purchased a used 1996 Mercury 150EFI. Now I'm trying to figure out how to rig it. The existing wiring harness has the Deutsch plugs, but the Mercury engine requires the round multi pin connector. I've looked for adapters but having trouble finding one. CDI told me they didn't make one. I also found some used Mercury wiring harnesses, but concerned that they may not fit the gauges in the dash. Do you guys have any advice or direction on what I should do?

Thanks for your help!
