Hey guys, scored a great sweep speedo off a poker game. Wondering what I will need to do to put this in my 66.

 

Sorry, but I have searched around and haven't been able to find any real wiring info.

Before you remove your standard gauge cluster mark where all the wires go. Then remove the cluster and install your custom cab cluster and hook the wires back up to the same spot as before.

The wiring is really quite simple. There will be a wire for left turn signal indicator, right turn signal indicator, high beam indicator, there are a handful of lights to light up the cluster when you turn your head lights on, and I believe two wires for each gauge, then you have an low oil pressure light and a charging system light (ALT). Right in the center of both clusters is a little silver box, that is the voltage regulator for the cluster; all of the gauges run on 5 volts verses the 12 that the rest of the pickup runs on. It is very important to make sure that part is on there. It has been a long time since I made the swap to a custom cab cluster so I don’t remember if my standard cluster had one, but since the custom cab cluster is plastic, there is a spot to run a wire to ground. If that is not there nothing will work on the cluster. Like I said I don’t remember if the standard cluster had one since it was made of metal.

The swap is real easy, just take your time and label the wires and plug them back into the new cluster. The speedo cable will hook right up to the new cluster.

BE VERY CAREFUL when tightening the mounting screws, as the custom cab cluster is plastic, VERY EASY TO OVER TIGHTEN THE SCREWS and you will crack your new housing.

I hope this helps you out.

Might I suggest purchasing a 'wiring diag. manual', found it invaluable rewiring my 65, and trouble shooting in event elect. problems arise. Purhased mine thru FTE shop, majority of the Ford parts supplier's have them, or you can go online and purchase from publisher, Jim Osborn reproduction. Don't waste your money on the laminated type diag.

As Jeff noted, make sure the 'constant volt. unit' is included. Can't recall which guages are included in the sweeping spedo cluster. May require wiring 'amp guage' circuit, and oil pressure circuit. Can use the oil pressure idiot light wire for the electrical oil pressure guage, but will need to change to a different type sending unit on the engine block. I kept the idiot light, made an adapter on engine block for the electrical type sending unit and ran a wire from sending unit to the guage. Don't recall if the sweeping offered the idiot light. May need to add light circuit, I duplicated the existing guage light circuits. Anyhow, sorry not very good at explaining, perhaps more knowledgeable member can explain better.

 

if the CC cluster has the additional alternator and oil pressure gauges you will need to get the additional wiring harness for these 2 as these gauges were not on all the trucks...

Its cool, got it all hooked up. Thanks bigblock and dave.
And camper, already had the harness for the oil and alternator, but this cluster didn't come with them or holes pre-drilled. thanks for all the info.

 

Funny thing was that it all worked fine during the day, but at night I thought aliens were picking me up again. Lights flashing weird and not working. Fixed the ground and all is fine.

 

There are a good portion of electrical problems on cars, equipment, trucks and so on that are caused by poor grounds. Weather they are loose or have corrosion. They are also over looked many times and the people trying to fix them are tearing their hair out to solve the problem.
