Just look for a ECU wiring diagram and see what pin broke off.

Yep, it's right, it's just the wires are all twisted.

That's exactly what it looks like he has there...mine bends down before the shock tower and goes along the side of the battery to the starter. I think it just looks weird with his pic, especially since they are twisted. @Casey Deckers can you post another photo of your battery/ shock tower so...

@BLACK'98DSM Are you referring to the ground wire from battery to chassis and starter? That's the OEM wire on the 420a. It comes off the battery, goes to chassis by shock tower first, then off there to the starter. It's right.@Casey Deckers I would get a loaner scan tool and see what codes...

Well as far as the OBD port, usually on most cars and trucks the OBD ports power is shared with the cigarette lighter if it doesn't have it's own fuse. I can't confirm that on a DSM as I haven't had it lose power before, but just putting that out there.

Front and rear bumpers bolt right on. You need the headlights and reverse lights. If you don't do the headlights you'll have a big gap where the bumper meets the headlights on the inside of them. Fenders, hood, and taillights don't need any modification.

@ipWitan You can always buy a usb wireless carplay dongle later. As far as suggestions, I always do a secondary battery by the amp, but that's me. I would do that or a nice capacitor just to reduce the toll on the cars electrical system on the hard hits, and avoid any dimming.

When you said "During test drive after motor mounts, RPMS would drop to 0 in neutral. Normal idle when stopped!" When the RPM's dropped to zero, was it just the gauge cluster going to zero, or did the engine itself drop in RPM's as well?

How does the Fusible Link 60Amp Alternator 100Amp fuses look. Any corrosion in them?

I was just gonna say the same thing about both the ground to the firewall not looking right, as well as the the wires to the terminals needing to be reterminated. However, instead of soldering and reterminating at the terminals, get some nice terminals like these.Amazon Terminals

I would check that ground wire from the bat to the firewall, and the ground point under it and make sure its clean of rust. Feel along the wire and wiggle it around, maybe its corroded from inside, gotten stiff, or is ripped/ severed. You should definitely be getting a tone as that is a ground...

Well looks clean...my only concern would be not getting anything on the continuity test on the firewall ground. So when you put it on that setting an touch from negative terminal and firewall ground you don't get any tone? Continuity setting on MM should look like a wifi signal

Have any pics of the battery and terminals/ engine bay?

Ok lets try this. How many ounces of freon is in your system currently?

Well according to the chart, and ambient temps, which for Nashville was 95 F today. The low side shouldn't be over 32psi. Your low side seems to be hitting 50 psi. You probably have too much freon in the system. That usually happens when you use those auto part store charging gauges. Evac the...
