1. The wiring method of the relay:
85 and 86 are the input terminals of the relay start signal (small current input), 87 is the output terminal (large current outflow terminal), and 30 is the source of high current supply (usually connected to the positive pole of the battery). When 85 and 86 have a signal (power on), the relay will connect 87 and 30, so that a large current will flow out from 87. If there is no signal at 85 and 86, the 87a terminal will be connected to 30.

2, the connection method of positive to negative
First of all, use the relay, not the thing in the anti-theft device. The one in the anti-theft device is called a circuit breaker, and the relay is a relay with 4 feet and 5 feet. Three feet are in a row, the first and third feet are 12V coils, the middle foot is the common point of the contacts, and the other two are in the same foot, one is normally open, the other is normally closed point.
The relay generally has an induction mechanism (input part) that can reflect certain input variables (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.); Between the input part and the output part of the relay, there is an intermediate mechanism (drive part) that couples and isolates the input quantity, processes the function and drives the output part.
