Ohm resistors in wiring harness

Post by Oneilln »

Hello I recently bought the Rockford Fosgate DSR1 and the maestro aCH2 instillation harness for my 2017 Dodge Charger with factory amp and Alpine audio group. I have read several accounts of people having problems getting everything to work properly and after further instruction from Rockford and or idatalink, they had to wire in 500ohm resisters into the wiring harness at the colored clips so that either the DSR1 or the 8.4” unconnect radio would sense a load. I was wondering if that is still necessary to do or has something changed since then to correct that?

The never revisions of the ACH2 harness have the plug in style resistor board included in them. You would simply plug it inline with the colored 2 pin connectors. If your harness does not have the plug in style, you would need the previously mentioned 500 ohm, 1/4 watt or larger resistors.

I do have the colored 2 pin connectors in the harness. Thank you for clarifying

They all have the colored 2 pin connectors on them. The newer versions of the harness have an inline circuit board that has 4 colored connectors in, and the same 4 colored connectors out of it. If you don't have that, then you would need to add the resistors directly to the harness.

How do I know if I have one or the other? Is there any visible difference between the two or on the packaging?

The packaging is the same. It was a running change in the harness production. What you would need to look for in the box is the part below.

I do not have that part with my harness. Am I able to purchase just that part or the entire new harness? If not then how would I wire the resistors in? In the + or - of each 2 pin connector? Or 1 resistor connecting the + and -? For example 1: +++=+++
2: -—=—-
3. +++=+++
. =
. - ——=——-

See attached. This is where you would attach the resistors.

So 1 resistor connecting the + and - for each color. Ok thank you

Also does using the extension harness change anything with the resistors?

Using the extension harness does not change how you would install the resistors.
