92 XJ code 35 won't go away

[XJRex1]

92 Jeep XJ - still throwin code 35 (bad relay) but everything seems to work - don't get it. Aux fan comes on with A/C and / or at about 240° 250° range. *new relay, new fan, new 20 amp fuse, new fan temp sensor.
One member suggested I disconnect the battery cables & and ground the positive and go thru a procedure but I couldn't find ground. Say Whaaat?

Disconnecting the battery cables and touching them together will clear any codes. Also remember a code will stay there as a stored code until it is cleared manually or after 80 starts. What it is sensing is a bad connection in the coil circuit of the relay. Clean up the contacts and put a little dielectric grease on them and it should help

Thank you sir- I get all skeet (ha!) dealing with auto electrics - don't want to screw nothing else up.
