What is this for?

[PlumCrazy]

I replaced the gauge cluster in my 94 four banger Ranger with a cluster from a Mazda b3000 (v6) so that i could have a tach

Everything lined up and plugged right in, it appears to work fine.

but i was wondering if anyone knows what the little circut board that clips into to back of the gauge cluster is for? it just slides in and has a clip


heres a link to a couple pictures of it

I was thinking maybe it was so they could use the same cluster on v6's and 4 bangers and just put the chip in that was matched to that what ever motor? so say it would read the rpms

That is called the Slosh Module - it adjusts for movement of the fuel level float. It keeps the needle in the dash from moving while the truck is in motion. In older cars when you would accelerate, brake or even turn sharp - the gauge would show more fuel or less fuel depending on the motion - this keeps the needle steady.
