The 14-1130 and 140-1130 are relay boards that have relays that route the power to the electric motors for your Slide Out System. This circuit board replaces circuit board model numbers 14-1130, 14-1098 and 14-1086. The same fuse and breaker that is on the old board may be used on the new 140-1130. The 140-1130 controller will need the center wire switch to be a 12VDC (positive trigger) which on some models of controllers such as the 14-1098 are ground trigger. 3- If you have the older 14-1098 board on your RV this ' be a drop in replacement. It's slightly larger (so you'll need to have new holes to screw it down) and you'll also have to do some changes to your stock wiring. If you do the changes this will function for your system just fine.
