Location for the ECU on 1972 Duster 340

[DustyEd]

Where was the original (factory) location for the ECU on a '72 Duster 340? I have seen pictures of different engine compartments and they are in various places. Any help would be appreciated. ~Mrs. DustyEd

72 is only year the ECU was mounted by the battery. Not an ideal location and in 73 it was moved.

Every factory 72 340 car I have ever had or seen was like these pics.

74 ecu was on the vertical rise of the fender but very close to the firewall. Just to give you an idea where they eventually decided to put it.

Really appreciate the quick replies!

Were the ECU mounting brackets only found on the E-bodies? Were their purpose simply for cooling the ECU and how effective/useful were they?

I have seen those cooling brackets on only 73+ B and E bodies. I've never seen one on an A body

I got my brackets from a 74 cuda’. 1 for ecu and 1 for the vr. Kim

So, did you use it on an A-body? Were these just for ECU cooling?

Your comment on the bracket used for a voltage regulator reminded me of my VR (dated 1973) recently removed had all of the "backing material" melted out of it!

I never did put them on anything. I think that was their idea. Kim

The 73 and up location makes way more sense because it gets the ECU away from battery corrosion and you don't sit on it to work on the engine

Calling the ignition module/box an ECU is a stretch...IMHO.

It does control the spark.

So it controls something, it is electronic, and is a unit. ECU.

Calling it a computer is the stretch.

Chrysler has called it an electronic control unit from day 1. Kim
