Update: So I think we've gotten past the final hurdle with the engine swap. The 3.7 fan relay for the radiator is different from the 4.7 relay. So, yes, the harness was repinned correctly for the 4.7 engine, but nothing was done for the harness connection to the fan. Whodathunk? The good news...- Honduras

HotwireAuto too care of the harness and programming for me. I explained what I wanted done, provided them with a 3.7 harness and ECM, and they took care of the rest. It was probably the easiest part of the whole shebang. No I would not do it again. The only reason that I undertook this...- Honduras

Yeah that's the sound of other cars being worked on in the background. That video is horrible. Still working on the radiator fan. Once done I'll make a better quality video showing off what it's really like. One thing I've noticed so far is that I'm going to have to upgrade my front coil...- Honduras

Problems with the ECM and the SKIM. It was a very easy fix but the issue was finding someone who had the right computer to reprogram the SKIM. it could've been taken care of a lot sooner but sometimes life has a funny way of reprioritizing wants and needs. :emotions34: All the gauges appear...- Honduras

I have dash cams in each of my cars. 720P recording. Records cockpit activity, too. To drive without one is insane.- Honduras

Well that makes it easier to diagnose but a pain in the butt to fix. So what do I do in this situation, box up the ECM, SKIM sensor and keys, then send it all out to a dealership? That'll take a good 3 weeks to pull off if that's the case.- Honduras

I wasn't expecting it to run perfectly. I knew there would be problems because of the O2 and oil pressure sensors not being connected, but I wasn't expecting it to cut off. I'll get the ECM reflashed later this week. The key fob was removed from the steering long before I connected the new...- Honduras

Routing for the dual exhaust setup from the headers was completed over the past weekend. Perfect timing! The only thing remaining to do at this point is mount the new engine. It will be on the road this weekend. Stand by for updates!- Honduras

Nothing yet. The replacement engine arrived at the freight port in Miami this morning. It'll probably take 3 weeks to get here plus clear customs. Don't know, maybe ready to get it rolling in a month.- Honduras

Just got off the phone with the folks over at Powertrain. They're replacing the engine free of charge! I was fully expecting a worst case scenario and have to foot the bill for the replacement! Talk about some amazing customer service! Looks like I'll be back in the shop in two weeks or so!- Honduras

The engine shipped with masking tape over the manifold ports. I looked at some photos that I had taken when I first got the engine and it appears that the spark plug holes were not covered. Man, what a pickle!- Honduras
