V1 No gauge lights

First time to turn key to accessory no lights on instrument cluster. Bought new battery today so should be good there.I wired the car myself based off what I seen on forums and videos. Iam sure I missed something

First thing is to check, if you have a healthy battery, is all grounds for attachment to bare metal, no paint or powdercoating under the lug attachments. Next is the large connectors that attach to the PCM/ECM and BCU, these have to be REALLY tight to seat well. Start there and let the forum know of any findings.

Will do tomorrow I’ll bring some tools and get after it.thanks for the input.

Not sure what lights you would get when turning to “accessory”. Or did you mean ignition on but not trying to start?

So I’ve got between .5 to .2 ohms resistance on grounds. Here’s some pictures. I’ve got three grounds dash attached to power steering frame. Three grounds attached to center frame rail. Only one ground in rear for starter. Sound right on that many grounds? Iam not missing a ground in the engine area? Everything feels bolted and latched down on connectors. Yes that key on crank or accessory pre crank no lights in cluster.

Bcm fuse 7 for instrument cluster power coming from b+ no power. Fuse .2 ohms. Will take new battery to work tomorrow to perform a charge/ state of health%. Old battery had a 2017 stamp and wouldn’t light a bulb so I just bought a Costco interstate. Out the door was $132 not bad.maybe I’ll take apart the bcm for giggles while I wait

This 50 amp fuse comes off the b+ right into the bcm. The battery states 12.45 bolts it probably good

Bcm fuse 16 ip ign no volts. Good fuse

You need to add your donor to your signature so we know what you are working with.
The later models have the cluster fuse and many other things fed by a 40 amp fuse in the main fuse box. The earlier ones are probably similar or the same.

Been awhile since I installed the red connector into the bcm. Found the 7 mm loose. Got power to cluster lights maybe I’ll crank her tonight. Always something elementary thanks all

Yeah man It cranked. No gas so I’ll do that next!
