I am impressed - those resistors are not +/-10% like normal resistors. They are more like +/- 0.1% or probably even better! I went through and measured ours - they were all exactly those values except for one. One of the 1270ohm measured more like 1270.5 with the display alternating between 1270 and 1271 - the rest were all exact. Rather than rolling our own, we are planning on using the board from the steering wheel donor just like Chad.

I don't think the resistor tolerances are all that critical. I think gold banded 5% resistors would be just fine. You're going to pay an arm and a leg for something that has a .1% tolerance. I don't even think that would be an option in your standard carbon film resistor.

I bought all of my resistors through Mouser. They are all metal film with .1 tolerance; were about a dollar each.

Did you have to buy multiple resistors to get the required values?

 

[Dre]

What power rating are y'all using?

 

[Brian74]

No; they had everything in single resistors.

We stock the resistors.

We are in Alaska right now but when we get back we can send you all of the proper resistors. We get back Monday.

Email Adam and let him know.

Thanks!

Years ago I did an engine swap on my Camero with a VAT that used the little resistor in the key to enable the operation. I too thought that the tolerance was not that critical. There were charts for the possible values. I used 5% resistors and had to custom make a resistor that worked by putting a couple of resistors in series to get the required value to make it work.

Also keep in mind that a potentiometer would work too. While not optimal for permanent installation, they would make it easy to dial in the correct resistance assuming using one with a relative close value.

Cruise return line on resistor side is just ground correct? Just want to ensure before I bundle the harness back together.

 

[Briann1177]

Yes.

Anyone have the pin info for the seat plug used on the dash panel

Are the Info and Return switches in the button panel normally open, or normally closed? I wired my switches as normally open, and they aren't working. Need to confirm this before moving on with debugging the panel. I don't have cruise control, but the hazard and horn are working fine.

I’m pretty sure they are normally open. You did use momentary switches for those in question?

Yes, momentary switches (not provided by DF.). I pulled them both to confirm the switches were working normally, and confirmed the value of the resistors.

The schematics show the DIC switches are normally open, but they tie to a ground not a 12V source. If they are switching into 12V the logc in the instrument panel will not see the correct voltage drop across the resistors.

Not sure which wiring diagram DS has posted, but remember that there are some differences in newer and older models. Doesn’t change his main point though.
