I've got a 93 civic ex in which I changed the engine from 1.6 to 1.5 and use a harness of a 1.5. My problem is my temperature gauge goes down a little bit when my lights are on and sometimes goes up when i rev it and one more is my clock resets everytime I turn off the engine. Do this have an effect to the wiring harness I put in or there's a loose ground somewhere cause I also changed my cluster.Any help will be appreciated. Thanks
