4. Splice the remaining wiring. Start with the White OBC Connector since most of these go to the Odometer side of the dash board. I used Heat Shrink for all my splicing and connecting. To Splice: I stripped about ½ an inch off the ends of the two wires I wanted to connect together and hooked the copper strands together in a joint and heat shrink the joint. To Connect or Tap Into: I cut the wire I want to tap into and strip about ½ inch off each end then I take the wire that is tapping into that wire strip ½ inch off that and join the three ends in a joint and heat shrinks the joint. So you will understand what I mean when I say “Splice” and when I say “Tap Into/Connect To”.
I. For the White OBC Connector these are;
a. White OBC Connecter Pin Slot 4 (Brown/Red); Splice with 3 feet of 18 Gauge Wire and run it towards the space beneath the steering wheel. This wire will serve two purposes; because the 18 gauge wire is stiff like a coat hanger you will use it to pull thru the smaller, softer 20 gauge wiring going to the Odometer. This makes that task a lot easier. Second, this will serve to tap into the BC Stalk’s Pin 10 Yellow/Red wire.
b. White OBC Connector Pin Slot 5 (White/Purple); Splice with 3 feet of 20 gauge wire, run to the Odometer and tap into to the White/Purple wire going into Pin Slot 12 on the White Odometer (X16) Connector. This provides computer data for the OBC.
c. White OBC Connector Pin Slot 6 (White/Black); Splice with 3 feet of 20 gauge wire, run to the Odometer and extract a female pin w/ pig tail attached from your old 7 or 11 Button MID/OBC Black Connecter and splice this pin’s pig tail wire to the other end of the 3 feet of 20 gauge wire. This female pin will be inserted into Pin Slot 21 on the White Odometer (X16) Connector. The pin is slightly bigger than the hole so you can either file down the edges some and push it in or push it in sideways like I did. Also be sure to check before hand to see that the Pin Slot 21 on X16 is indeed empty and doesn’t already have a wire going into it. If it does have a wire you can just tap into that wire. This provides all your Gas data (refill, consumption rate, etc…) for the OBC.
d. White OBC Connector Pin Slot 7 (White/Yellow); Splice with 3 feet of 20 gauge wire, run to the Odometer and tap into to the White/Yellow wire going into Pin Slot 11 on the White Odometer (X16) Connector. This provides computer data for the OBC.
e. White OBC Connector Pin Slot 9 (White/Grey); Splice with 3 feet of 20 gauge wire, run to the Odometer and extract a female pin w/ pig tail attached from your old 7 or 11 Button MID/OBC Black Connecter and splice this pin’s pig tail wire to the other end of the 3 feet of 20 gauge wire. This female pin will be inserted into Pin Slot 10 on the Blue Odometer (X17) Connector. Be sure to check before hand to see that the Pin Slot 21 on X16 is indeed empty and doesn’t already have a wire going into it. If it does have a wire you can just tap into that wire. This provides all the Speedometer data (average speed, distances, etc…) for the OBC.
f. White OBC Connector Pin Slot 1 (Black/Green); Splice with 4 feet of 18 gauge wire and if you have removed the glove box already you can poke this thru to that area and leave it there for now. If not you can just set it aside for now. This has to do with the CODE feature. This connects to the Car’s Alarm for the OBC’s CODE feature to work in conjunction with the Central Alarm Brain.
Just pull the pins out. I broke my old OBC Black Connector with a hammer to loosen the pins up some and pulled the ones I wanted to use out.
