ZJ Gauges Compatible with XJ Computer?

I'm in the process of swapping an OBD2 4.0 from a '98 XJ into my '86 CJ. Here in California, I need to have a functioning CEL in order to pass smog and get registered. I understand that the PCM does not have a direct CEL output, but rather sends a message out on the CCD Bus, and the Gauge Cluster receives and interprets that message to turn on the CEL. My plan is to use a '98 gauge cluster to get the functionality I need, basically creating a "Black Box."

I do not have the gauge cluster from the donor vehicle. My question is, will a ZJ gauge cluster be compatible with the XJ PCM? Or, another way of asking is, are the CCD Bus messages the same between the XJ and ZJ?

I ask because there seem to be a lot more ZJ gauges available out there than XJ. Thanks.

Xj computers do not seem to work in zj's. So probably not going to work with the gauges.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.
