I just did a full harness swap took a DC integra cabin harness, underdash and engine harness and DC cluster and put it in my 90 EF hatch. It runs good was pretty simple to do but I seem to not have working brake lights and my dash lights aren't turning on in my DC cluster. I know I need to plug in the hazards for my blinkers to work but not sure on the others. Wondering if anyone knows the answer to my issue. Thanks in advance.
Oh and my gas gauge isn't working either but my fuel pump is.

 

What dash harness are you using? Are you using the ef or the DC one?
