Which wiring harness - 1929 CCPU

My CCPU project has no wiring in it. So, I'm in the market for a complete harness and am looking at my options at Mikes and just want to double-check my logic.

The options for my year are:
One Bulb with Cowl Light
One Bulb with Cowl Light & Turn Signal
Two Bulb without Cowl Light
One Bulb without Cowl Light & Turn Signal

Since I have no turn signals or cowl lights, is it as simple as: Two Bulb without Cowl Light?

If I decide to add cowl lights later on, is it an easy modification of the Two Bulb kit, or should I get the One Bulb with Cowl Light kit right off the bat?

Thanks in advance.
 
Do you have a steering box and column?
A light switch? 2 tooth, or 7 tooth? Do more research before you buy.
Do you own any books, or the judging standards? Belong to a local club?
Have a restored pu nearby to use as a template?
Slow down a little and save false starts.

You have to look inside the headlight buckets, and see if your reflectors have two bulb sockets or one.

My 29 ccpu has headlight bulbs and parking light bulbs inside the bucket...

I'm not sure but I think the rotary switch on the steering wheel is different for single bulb verses 2 bulb...


I just yesterday ordered a harness from Bert's... http://modelastore.com/

And I agree about the cowl lights..too fancy for a pickup!
 
Here is a picture of my light switch handle....it has one position to the left for parking lights, and two to the right, low and high beam.

Also a picture of my 7 tooth steering box,

And finally the headlight reflector..

I have been trying to sort my headlights since I first got the truck last spring..I had a mix of 28 single bulb buckets and two bulb reflectors and harness....

Take it slow, as previously advised!!

As Bill said, buy the two bulb harness with no cowl lights. I wouldn't add cowl lights, but if you did, then you could just run a separate switch ad the dealers did in the old days.

You have a 7 tooth steering column, but have you looked at the switch to be sure it's made for the "TWOLITE" system?

Tom, he said he has one position to the left for park, and two to the right for high and low. If he also has an off position where the photo shows the lever, than he has the later twolite switch.

Those are my pictures, not Nathan's!

I posted them to help Nathan identify what he has....

I don't know how you sorted out the headlamps, but I would go with what it should have for the time period. No "TWOLITE" on the buckets until February 1929, and they would have the single bulb reflectors. After that they would have the TWOLITE on the buckets and have a 2 socket reflector, or have cowl lights and a single bulb reflector. And pickups and AA's would have painted buckets, except for a deluxe version.

Also the 1928-early 29 would have the early headlamp switch with high, low, and off positions only.
 
It's a late January 29 pickup...close enough to February, or did they start the Twolites on February 1st, 1929?

This is Nathan's thread.

Direct comments to Nathan's issues..
 
I suppose a vehicle built near the change-over date for any item or model year could have earlier or later parts or a mixture of both.

We are going by the engine number stamping date, which may have not found a frame for some time.

Lots of possibilities
 
Is your taillight the later teacup or the tuna can like all 28's have. The tuna can, fluted headlight lens, 28 style headlights with single blub was used on the early 29's thru February; it used the second generation light switch which only has 3 positions: 1 position left for park, center off, 1 position right for driving ( no high beam), headlight blubs 21-3 candle power, the light switch is much different than the later 2 blub 29 style, the wiring harness is also different than the later 2 blub style.
