i never had a problem with Oceanic....they helped me with a few problems i had on my rex over the years and ive seen some really sick motors come out of there and the cars were equaly as nice....... most amutures can do a multi point swap so i dont doubt that you prob. baught a fucked up car to start with.....get a new harness if its that big of a deal.....

and yes your problem is wiring....
