All the gauges and the bracket are from Autometer, but I pieced them together since they didn't sell these three as a kit. Install varies between easy (vac) and "involves welding" (wideband). The water temp gauge is electronic with its own sensor installed in the upper radiator hose. If you want to save a few bucks they have gauges where the sensor is a probe and it has a line full of conductive fluid or something - seemed to sketchy for me so I paid a little more to just have regular old wires. FYI watching the air:fuel mixture in a carbureted truck is pretty eye-opening. There's zero guesswork in tuning the carb and emissions system. Here are links to what I have:Great work! Can you tell me what you used for the vacuum and temp gauge cluster? Is that three gauge system something you made or picked up? That is just what I’m looking for.
Wideband Air:Fuel Gauge
Water Temp Gauge
Upper radiator hose adapter for water temp sensor (cut the upper radiator hose and install the adapter, sensor threads into the adapter - get creative with grounding the sensor, I'm using a ring terminal under the mounting bolt for the ABV/smog equipment)
Vacuum Gauge (Comes with it's own single-gauge bracket that I threw away)
Yes, I painted the trim rings on the wideband and water temp gauges black to match the vac gauge! For power I split the main 12V wire coming into the cab before it hits the fuse panel and ran that to its own fuse panel tucked up by the blinker relays on the driver's side kick panel. It's a small 6-fuse unit and it feeds the power to the water temp and wideband gauges, in addition to fuses for my head unit and bluetooth receiver. I built a harness to go from the kick panel to the center of the dash to keep things organized. You could go full OEM and wire the unused fuse panel spots, I just never got around to that on my tomato truck. Matilda has the glass fuses (82 was the last year for that) and only one extra fuse spot so I no longer have room. For the backlights I split the cigarette lighter backlight wires and made a mini-harness that feeds all three gauges. The cig lighter is on the dimmer circuit so they dim too! I probably should have found the dimmer wiring over by the fuse panel and ran that over in the main harness, but ... I didn't.
If you need to pick my brain about any of it, let me know.
