Speed sensor 2x what actual is

[Spaz5spd]

I recently dropped in "new" speed sensor, I cut the pig tail and soldered onto original harness since I have a 95 that had different pin style. My speedometer read out roughly 2x the speed I'm traveling at. Is there a specific reason why this is happening?

The neon speed sensor will make the speedometer read faster.

Same experience here. Neon speed sensor was installed.

Dam grabbed it off a junked eclipse too... Ok guess I'll grab another one
