That is your ASCD , its basic tells the ECU what gear the automatic trans is in. You don't need it but if you want to get rid of CEL's you need to jumper it. There's a walkthrough around here somewhere. I do believe (but not 100% sure) that it also controls the cruise control. Again not necessary but rewiring it gets rid of the CEL's it throws and pretty sure it gives you cruise control back.
