The 20049 one looks like the one that is on my Factory Air 1990 LPlus. I can read to numbers on mine (2070 and 10J11)
Mine has four connectors but the wire that plugs into it has only two wires and two connectors (The two across from each other that are closest together).

The are four connectors but there are only two wires on the plug that connects to it, the two opposite each other that are the closest together.

Thanx a bunch will research those numbers I did install the 20927 and a/c works great again It did pass the low speed fan low pressure cutout at 25 psi according to my gauge. I had already changed over to the 134 years ago. again thanx
