Silverfox99,

Did you sort out the issue?

Are your harness and car both OBDII?

I am doing an OBDII/OBDII swap and am unclear whether any pin modifications are needed.

I have an EVAP valve CEL code but other than that it runs and drives.

I thought the only wiring mods needed were for OBDI to OBDII and/or Auto trans chassis.

I have not found a definitive answer or pinout diagrams that make it clear.
