I've got an 86 BMW 325e up in Dallas that is awaiting a much larger, more modern, more powerful engine (M54B30 for anyone who knows BMW's). Just need to get it down here.

Well, hate to be a downer but this morning I decided it was time to move on with the Pathfinder. I found some major rust holes in the floorboard and the wiring is just way too much of a basketcase. I was able to pull off as many good parts as I could though. So off it went this morning. Don't know if I'll get another or not, but it was a fun ride while it lasted. That was the longest I've ever owned a vehicle.

Not since the weekend, between class and work I've been swamped.

Double post

Nice work

Not sure how much energy I have to put towards this today, it's really hot out, and it's mentally taxing, but I've got most all the snipped wires isolated, and the good news is they all go to the main bundle of wires that heads up the dash, so it shouldn't be too difficult to figure out I think. I know one set of the wires will be going to the main relay box on the passenger side of the engine bay.

ECU harness is eliminated now, with the exception of wires I felt needed to be kept. I kept the wire that goes to the transmission control unit, all wires associated with A/C, wires going to various relays, the MAF wiring (in case I felt the urge to use it), the tach wire, and the VSS wire. Might be some I'm forgetting, but that's decent progress.

I finished pulling the dash out today, so I have full access to the wiring now, but man is it scary. I did find one error in my attempted rewire though, the alternator connector is currently wired to the ignition switch fuse instead of the battery. Whoops.

I'll probably spend some time tomorrow digging through the harness... Not looking forward to it at all, but I really want my Pathfinder back on the road, it's been a year now. This is the longest I've owned one vehicle, but it's also spent about 75% of the time I've owned it parked Which is sad, because I really love driving it, it's been fantastic when I've needed it most. I especially want to get it running because I got a Grasslinks 4x4 center link I want to try out.

Should be able to power it now, just had to install a $1 transistor.

I've ditched the stock wiring for the engine, I wired the Megasquirt directly to the stock connectors. I'm doing MAP+IAT (and taking the manifold to my shop today to drill and tap for the IAT). I am going to have to figure out how to keep the dash/interior power working and how to get switched/fused power to the Megasquirt though. Here's where the Pathfinder sits right now: I pulled the entire engine harness through the firewall. I had been trying to fix the old harness by splicing another Pathfinder's harness in at the firewall, but the wires didn't all match and it got much too complicated to actually repair. Ditching this and wiring the Megasquirt directly makes it a LOT simpler under the hood. I'm also still converting it to sequential ignition via LS2 coil packs. I've got the entire FSM in my OneDrive, had originally used it to wire the Megasquirt, when I was going to use the original harness. Oh, and I found out yesterday my idle air control valve is dead, probably been dead for a long time. Not absolutely necessary for the Megasquirt, but will definitely make it more civil, so I've got to replace that. I had to modify the Megasquirt a little bit to work with the distributor's optical sensors and also work with the IAC (since it requires more power than the standard IAC setup allows on the Megasquirt). Lots of progress over the last couple days. Oh... and yesterday I went to open the drivers side door, damned door handle snapped right off.

Over a year later and I'm back at it. I manually repaired my Megasquirt, was really glad I could salvage it. I've been working all day on wiring it up to work on the Pathfinder. I've got most of the work done now, it connects to TunerStudio, the modules I've connected work, and I'm ready to start installing. Only thing is I've got to sort out the main harness, its in shambles right now, so I've got my work cut out for me.

The stock ECU died. I never got it running on the Megasquirt, my Megasquirt needs some repairs, some of the traces came up.

Ugh. Water pump just siezed up on me... Glad I have AAA and was close to my mom's.

I literally just got my Pathfinder on the road again this weekend, it's been sitting for 9+ months in Dallas (at my mom's) while I've been living in Austin. I'll be able to resume working on it when I can get it back down to Austin (probably next time I come up to Dallas). Sucks not being able to make progress but keeping my life on track has been more important.
