CRAP! Sorry guys, I completely forgot about you! Here is the wiring diagram I drew up, I am posting it large so hopefully you can read the colors and components:
Here is the quick n dirty of how I wired things up;
Jeep bulkhead wires:
4 Red and Red/white stripe wires - These are constant 12V into the fuse block. I wired each of them through a fuse (30 amp each) in my fuse block
Yellow - This is switched 12V out from the Key switch. I used this wire to power all my relays (pin 86 - through its own 20 amp fuse). This wire also connects to the Light Green/Black stripe wire on the PCM.
Orange - This is the power out from the fuel pump relay (pin 87) to the fuel pump. I wired the Brown/White stripe wire (negative PCM output) to the other side of the fuel pump relay (Pin 85). The constant power into the relay (Pin 30) comes from its own fuse in the fuse box as well.
Light Green - Oil pressure sender output to gauge, I shortened this wire as it was in a spot closer to the firewall than on the 4 banger.
Purple - Coolant temp sensor for the gauge, I had to extend this wire to reach the front of the block on my V8.
Dark Green - This is the start solenoid wire. I wired it directly to my starter solenoid as I did not want to use any kind of starter interrupt (having clutch depressed, etc) in my system. If you want to install a clutch switch that has to be depressed in order to start just wire the Dark Green wire to one side of the relay solenoid (Pin 86) and to the relay input pin (Pin 30). Connect a ground to one side of the clutch switch and the other to Pin 85 of the relay. Connect Pin 87 to the starter motor. Voila, will only start with the clutch depressed (pushed in for you laymen
The Green/White stripe wire is the tach signal input to the gauge. I connected that directly to the Gray/Light Blue striped wire from the PCM. Note that the PCM outputs a DIGITAL signal and the pre 91 YJs have an ANALOG tach so they are not compatible and your gauge will look like mine, limp. To cure this I aquired a tach out of a later YJ, I already had a guage pod with a speedo from a later YJ so I will wire those in place of my existing gauges (I want an electronic speedo anyway). If you are wiring an electronic speedo you will need to tap into the White/Orange striped wire and connect it to the existing speed sense wire (sorry, color unknown as I have a speedo cable).
My Jeep did not have a CHECK ENGINE light (or MIL). I will wire one in with the new guage pod and it will be wired like this; The light in the gauge gets a switched power source. The output from the PCM is a ground so the Black/Pink stripe wire will be connected to the other side of the lamp.
For the PCM there wasnt much extra to wire up. I left all of the sensors alone, with the exception of not using the black wire from the VSS (using a 2 wire instead of 3 wire). So basically for the VSS I am just using the Orange and the White/Orange Stripe wire to signal the computer that movement is occuring.
There are several Black, Black/Brown stripe and a couple Black/Tan stripe wires spread across the harness. A couple of those ended in an eye terminal that bolted to the back of the head. All of these wires need to be grounded however you choose to do so. The 4 that came out of one of the PCM connector I simply connected together in an eye terminal and used one of the PCM mount bolts as its ground. The ones behind the engine simply got bolted to an open bolt hole in the head.
The only thing left to cover is the Auto Shut Down (ASD) relay which powers all the sensors. There are 2 wires from the PCM to this relay. Thoughout the harness you will see Dark Green/Orange stripe wires. This is the power to all the sensors. Find one and tap into it. This tap will connect to the output of the ASD relay (Pin 87). The Dark Blue/Yellow striped wire is the PCM ASD output that connects to pin 85 of the ASD relay (keep in mind pin 86 is powered by my keyed power source through the fuse box). The fuse input (Pin 30) is powered through its own fuse in the fuse box.
Ask any questions if I managed to confuse anyone. Once you understand what is happening, its really easy to wire and put together.
