2.2.2
Make sure the type of fuel injector connectors
Before proceeding with the installation make sure your vehicle's fuel connectors are compatible with the contents of the product
package. If the connectors do not fit please contact the seller.
2.2.3
Check the polarity of the injector connectors (FIGURE C)
Check the polarity of the injector connectors so the wiring harness can be connected correctly. Use multimeters conductivity position
(beep-position). Normally positive side (+12 V) has the same wiring color.
Measure all the connectors same way. Remember which terminal made the beep sound. You will need this information further.
2.2.4
Connect the male connectors to wiring harness (FIGURE D)
Check which way the male connector plugs in. Push the red wire of wiring harness to the male connector. Make sure the red wire goes
