Part 4 Continued...
II. For the Black OBC Connector these are;
Black OBC Connector Pin Slot 6 (Blue/Brown/Yellow); Splice with 3 feet of 20 gauge wire, run to the Odometer and tap into the Blue/Brown/Yellow wire going into Pin Slot 26 on the Blue Odometer (X17) Connector .
Black OBC Connector Pin Slot 8 (Black/Green); Splice with 4 feet of 18 gauge wire, run to the Glove Box area or set aside. This wire goes to Pin 12 of the ZKE Module or Pin 12 the CBE Module X10182. This has to do with the CODE feature.
Black OBC Connector Pin Slot 9 (Green/Blue); Splice with 3 feet of 20 gauge wire, run to the Odometer and tap into the Green/Blue wire going into Pin Slot 4 on the Blue Odometer (X17) Connector or the Green/Blue wire going to Pin Slot 13 of the White Odometer (X16) Connector. I think this has to do with powering the OBC so either Pin Slot on the odometer connectors is okay. I choose Pin Slot 4 on X16.
If you have a 7 Button OBC and you want to install the Check Control then you will need to Splice 4 feet of 18 gauge wire each to the wires coming out of Pin Slot 3, 4 and 5 (White/Green, White/Blue and White/Grey) and run them towards the glove box area. Also Pin Slot 1 and 2 (Brown/Grey1 and Blue/Red) will have to be connected to your Brake Light wiring to activate the Check Control for the Brake Lights. I did not bother splicing these two wires with extensions since I didn’t know where to connect them and no DIY currently tells you how to wire them to the Brake Lights for Check Control. I will add info about this at a later date if I figure it out.
Open up your Glove Box and remove it, via a set of star point screws along the edges (two are hidden in the vents) and bottom and the 11mm Bolt hidden above the glove box light (not the flashlight the light). When you release that 11mm bolt the Glove Box will just come out.
Now if you had the 7 Button OBC you should have about 5 newly spliced 18 gauge wires coming thru from your new 18 Button OB’s White and Black Connector. Three wires go to the Check Control Module (if you have it, if not you can just seal off the ends and leave the wires in there in case you want to add the Check Control at a later date)-for the folks with the 11 Button OBC your Check Control should already be pre-wired if you had Check Control and you should only have only 2 newly spliced wires, instead of 5 newly spliced wires, coming thru to the glove box. These other two wires go to the ZKE IV Module (More specifically the Black/Green wire that snakes between the modules and have to do with the CODE feature. If you had the 11 Button OBC, then you just have the two CODE feature wires to connect to the ZKE IV Pin 15 and Pin 12 or wherever you find the Black/Green wire. So far I haven’t any luck in this. I think I found the ZKE IV module and connected a fat female connector pin to the end of the Black/Green Pin 1 wire from White OBC Connecter and pushed it into Pin slot 15 on what I think should be the ZKE IV Module and my CODE feature has not worked. Also I have an aftermarket Alarm wired to my car so I’m not sure if that even effects it. At any rate, you can also tap into any Black and Green wire you see snaking thru there and see what happens. Although all the various DIYs all disagree on where the ZKE IV module is, what color it is and what to do with it once you find it, they all agree that the target tap in is a Black/Green wire. The Bentley Manual also backs that up. So that is my next step towards getting the CODE feature to work. If you find you ZKE IV module for sure then you can extract two Fat Female Connector Pins w/ pigtails from your old Turn Signal Stalk, splice on the wire coming from Pin 1 on the White OBC Connector and Pin 8 from the Black OBC Connector to the pigtails and push them into Empty Pin Slots 15 and 12 respectively on that module. Some DIYs also claim that Pin 15 and/or Pin 12 on the ZKE IV already had wires coming out of them. If any of those wires are Black/Green then your work is a lot easier because all you have to do is tap into them and you are done.
