Deny, Look at the pins (blades) on the bottom of the flasher. They have three letters by them that stand for different parts of the circuit. A replacement flasher must have the letters on the pins the same. Some manufacturers used different letters for the different parts of the circuit so you will have to check online. If the pins are in different places on the flasher you can change the wiring on the harness to make them work. If electronic flashers are hooked up wrong they can burn out immediately and become useless.
Usually + or B will go to the positive side of a battery. L will go to the lamp through the switch. P is for the indicator light on the switch. I say usually because if you bought a flasher for a positive grounded battery then it could be different. Point is that the pins can be in different locations and if an electronic flasher is hooked up wrong, it can be trash.
Another problem with electronic flashers is that too much current can burn them out pronto. Check the rating of the flasher and measure or calculate the current that your bulbs will take. I = W/V
I have not had very good luck with electronic flashers and have just added resistors for the vehicles I have changed to LEDs.
