[QUOTE="jeepvid19, post: 425145, member: 18608"] Hi! New in the forum thank you! Doing a engine swap from a 1987 4.2 TO a 4.0 DONOR : 1995 YJ, engine 4.0 with a AX15, ECM, dashboard, fuses box (in-out), gauges & cluster, HARNESS WIRINGS Engine-under Dash,-rear lights. The front lights harness from the 1987. Actually finished with the installation of the engine 4.0-transmission-wirings under the hood and dash There are some things that for now I can’t connect: 1- the reverse switch (don’t know how to do it) 2- brake switch connector 4 pins ( can’t do it the old switch 1987 is only 2 flat males) 3.- fuel pump getting a external w/filter to do it soon. Everything else is hook, I connected the battery to see if it crank .... NOTHING! No click or anything! the only things looks working are: voltage gauge, dome lights, ignition switch turn on the brake light and seatbelt. Where and what should I check and how. PLEASE All help is welcome... thank you! [ATTACH=full]115539[/ATTACH] [/QUOTE]
