Even though this weeks progress isn't even really worth a post, I suppose I will ad the few pics I took,
While I do still have a little plumbing left to do, wiring is the next big part of the build, & I spent a ridiculous amount of time laying this out in my head over the last week,
Over two full days just staring at the thing, deciding where I need power, how much power/capacity, how that is going to effect, or get in the way of other systems sharing the same space, (harnesses, plumbing etc.) jotting down notes, & even a little bench testing of a couple components, (Ford wiper motors from the late 70's have some interesting stuff going on in them)
Before I got wrapped up in electrical, I did get the transmission plumbed to the cooler, & the water side plumbed to the engine, But no pics of that,
I also finally got a tab cut out, welded to the chassis, & a small turn buckle built for adjusting the alternator,
I guess that's what kind of inspired going the electrical direction, but before running any wiring I need to get as many of the electrical components mounted as possible,
Anything inside the cab will be about the worst to work on/install (since I never think to install door bars way later in these projects) So I started there, the rear steer pump & valve are already mounted, I just have to get a power wire capable of handling the current requirements of the pump to that location. Fortunately when building the floor gussets, & skins I made both sides symmetrical, so where there are two holes on the passenger side of the pump for the solenoid valve bulkhead fitting, there are the same two holes on the driver side, I figured one would be used for the pump vent, & the second for an electrical pass through, I did have to drill the hole a little bigger, then add a couple drill/tapped mounting holes to hole the pass through in place,
I also settle on the mounting locations of both the ARB compressor for the diff locks, & the MSD 10 ignition box, both will be behind the seats, the compressor behind the driver seat, & ignition on the passenger side,
Here you can see the compressor with the solenoids installed, (Also seen in the pic is the electrical passthrough installed)
As you can see I did play with the locker plumbing a little bit since the compressor was in place, the short line going to the bulkhead fitting will continue on to the front diff, the longer hose loops back over to the passenger side, where it will exit through the floor with another BH fitting, then it will be paired up with the rear steer sensing cable, & continue down to the rear link bar,
The compressor fits really nice behind the seat (when it is installed) & leaves the pocked in the floor open for other options later,
On the passenger side the ignition box will actually be mounted in the pocket, I was going to put it under the dash, but this location is better for mounting (The box will actually be setting on the mounts, rather than hanging from them) also put's it closer to the coil & distributor, where the majority of the wiring coming out of the box goes anyway.
No pictures of the box mounted yet, but I did snap a pic after getting the bulk head plug for the wiring installed,
There are several more pieces that need built/installed, like a switch panel for the rear steer mode switch, & locker switches, these three will be mounted close to the shifter so they can easily be reached on the fly.
As I mentioned I also made a few notes on the wiring as I though about stuff, A good example of that is the rear steer & locker wiring, all of this will be independent from the rest of the wiring in the truck, & this RTC setup is going to be different than those I sell,
This kit will have 2 modes, the standard mode like the rest I sell, (returning to center requires pushing/holding a button until the steering is centered where is stops & you can then let off the button) then the second mode will be auto center, I'll be able to turn left or right & have the rear steer automatically return to center as soon as I let go of the steering button/switch,
I drew the schematic out for this system quite a while ago, & even wired a couple for people for testing, (I don't normally sell RTC kits with the auto center feature)
Even though a schematic is great for figuring out the circuit & what has to hook where, It does nothing for actual wire routing,
So I sat down & drew a couple wiring guides, based on where parts of the system are mounted in this truck, & what electrical components I'm using to build the harness,
Here is an example
Now a guy could use this as a way to figure out how the system works, but it's really just a map of how I want to route the wiring out of the back of the relay box when I get that far, this should save a little time when I start crimping pins & routing wires,
I also added the pin numbers for the plug at the shifter (steering control) & labeled or color coded other parts like the solenoids & sensing unit plugs, just to simplify stuff later,
If people are interested I'll go into more detail on what parts I use & how the harnesses are built when that time comes,
But for now I have 5 days at the paying job before I get back to staring at this thing.
