How do you change the ECM in your 1993 Chevy 1500 pickup?
Pull your glove box. Located on right. Disconnect 2 wiring harness's then unit will slide out with a little "wiggling". New ecm will need you to pull the prim , rubber stops and clips from your old ecm and replace on new ecm. Most parts stores will let you use tools at the counter to replace right there.
