Many used items in our picture(s) have been cleaned and/or bead blasted prior to being photographed to show condition and detail. The item you receive, in most circumstances, will be pulled from the donor car and shipped to you without being cleaned. We do not retake pictures each time a used item sells. Pictures are a good indicator of what you will receive, but not all used parts age the same. On high dollar parts, email us and we can send a few pictures of the actual part available.
"Core" Items: If we use the word "Core" in the title of the product, the item has been deemed rebuildable, but has not been rebuilt. The item you receive, in most circumstances, will be pulled from the donor car and shipped to you without being cleaned.
This is referred to as the "K7" relay in the Ford service manual. This relay causes the flashing action of the 1967 Mercury Cougar instrument panel indicator lights. The number stamped on this relay is C7WB-13A366-A, the Ford part number is C7WY-13A366-C. We have these relays tested and ready to ship.
A quick bench testing: There needs to be continuity between the 'H' post
and both 'B' and 'S' (separately). We test them with 12v to the 'H'
post and the base grounded. 12volts should be read on both the 'B' and
'S' terminals. After this test, we put a 4 bulb load on 'B' and 'S' terminals and make the relay function. *CAUTION*
The 1967 and 1968 K7 relay look similar, but are not the same. Damage to your wiring system will occur with the wrong relay.*NOTE*
