where is the best place to get a wireing harness for my 370hp merc engine?

Try this place I bought two of them........http://bpi.ebasicpower.com/c/ALL6I/I...anel+Harnesses

did you buy two for your fountain.if so,witch ones?

Yes I did part # MAR6199-01-06

Now if you need the square mounting bracket on the harness this is the one you need MAR6199-02-06

thax face-it,thats alot less than my local guy could do for me.did everythang wire up ok?was your boat a 12meter or just 40?thanks

Its the 12 meter everything wired up great

thanks for your help.just ordered my harness.what size blower?250 or 420?the headers are nice.i wish i could have found a set for my ride instead of the ss marine w/dry pipes that i will be using.good luck w/your 12meter.brad
