The No. 7 wire is used to

Explanation:
The No. 7 wire is used to close the PUSH-TO-TEST circuit. When you press the test button, the test path must be completed so current can flow through the indicator lights to verify they’re working. The No. 7 wire provides that conductor, carrying power through the push-to-test switch and into the indicator circuit so the UP indicator (and any associated indicators) lights up during the test. This function does not relate to opening the UP indicator circuit or controlling the normal gear-position signals; its sole role is to close the test path and energize the indicators for a quick functional check.
