8. Prepare to splice the two (2) inline fuse holders into the red wires by cutting the red wires again, at
approximately three (3) to six (6) inches from each end.
9. Strip all wire ends back approximately ⅜-inch each.
10. For the HFB-type waterproof fuse holder used with the MRU, place a fuse holder shell on each wire
so each large end of the shell is towards the wire end, then add a fuse holder terminal onto the
stripped portion of the wire end.
11. For the HEB-type water-resistant fuse holder used with the LBPA, four (4) short pieces of heat shrink
tubing are included with the fuse holder for insulating crimped fuse holder terminals.
Place a piece of this tubing onto each 6-AWG red wire before crimping the wire end to the fuse
holder terminal. Two pieces of tubing at each crimped terminal may be used, if necessary. Next,
observe line/load labeling on the fuse holder and place the correct side of the holder (with terminal)
onto a stripped wire end.
12. Securely crimp each fuse holder terminal to the wire end.
13. For the HEB-type water-resistant fuse holder used with the LBPA, continue by shrinking the heat
shrink tubing(s) over each crimped terminal. No metal of a crimped terminal should be exposed after
completing each fuse holder-to-red wire connection.
14. Label each fuse holder and red wire appropriately (e.g., “MRU: 15-AMP FUSE” and “LBPA:
30-AMP FUSE”).
Do NOT install fuses into the fuse holders at this time.
15. Crimp an appropriate electrical terminal to each short red wire. A ⅜-inch ring terminal is included
with each cable for this purpose, but another terminal type (not supplied) may be used if required.
16. Connect both ring terminals directly to the battery’s positive post, or if present, to a stud on the
battery’s main/non-switched power distribution terminal block.
