Hey guys - I needed to replace the water temp gauge in my NAS 110 and checked out the link on the ECR site - http://www.eastcoastrover.com/signalconditioner.html
. The conditioner in my truck has been removed. I installed the AMR2631 gauge, but I am a little confused about which sender to use. I ordered sender part number PRC7918, but noticed that this sender is red, not white. Also confused that some of the previous posts state to use the AMR2631 gauge and PRC7918 sender in order to reproduce the set up in the 1994 NAS 90 trucks, but your site states that the PRC7918 sender "is found in most NAS Defender 110 engines will cure the problem and show you accurate coolant temp. information. This change duplicates exactly the later Defender 90 temp. gauge, a system that was designed without any signal conditioning."
I'm a bit confused as to which temp sender to mate with the AMR2631 gauge to give an accurate reading.
Anyone have a 94 D90 parts manual and can tell me the LR part number for the sender unit in that truck?
Any suggestions guys?
