I looked at old one it had 3 flat and 1round pin.
ANSWER Hello James. The left side on the range should have been a grill, not a surface unit. For the surface unit use on the left side, if the switch test good on the large and small elements, you will need to change the terminal blocks to work for a 4 pin cartridge, according to the manufacture. I sent you the service manual for the cartridge. Hope this helps.
