[QUOTE="weikee, post: 2429514, member: 34166"] Today since nothing much to do , i change the ecu ground lugs, and also reground (not normal grounding -ve to body and engine). What you need, -some Lugs "sliver lugs its better" you need minimal 6 that can fit size 10 bolt -size 10 spanner or T, (if you change your battery -ve bolt, need the correct spanner also normally its size 13) -1 Meter earth wire (no need expensive) go electric shop buy awg 10, or awg 8 wires also ok (like the amp cable). cost no more than RM 5/Meter. I use my old harness wires (from my previous car) -Solder Iron, and lead. best its 40 to 50watt - PVC Tape, get the high quality one. I use 3M High Temp tape (can withstand 130c heat :biggrin: ) this its the same tape i use when building a S13 track car some years ago. You normally can get it at the electric shop selling high voltage cable. (pasar road got). What todo 01) Open the top Engine cover (for A32) 2 nut and 1 bolt, you will see 4 earth wires, connected with 4 lugs. after so many years of driving the lug and cable contacts will not be good, especially this lugs and wires are not solder. 02) replace the lug with the new silver lug please solder the lugs. Tape the wires, doing so will prolong your wires due to excessive heat generated by your engine. 03) make one earth cable using the 8awg wire and lugs. 04) connect the custom made cable to the same location the ecu earth its. 05) bolt the lugs together 06) Connect the other end of your earth cable to your battery -ve terminal. 07) Close your engine cover. To make things simple Before ECU---------------Engine After ECU----------------Engine--------------(-ve Batt) [/QUOTE]
