New connector kit+$85Fresh OEM-style housings, terminals and seals on every plug — no 30-year-old brittle clips.
Upgraded injector clips+$40New locking injector plugs — the originals snap if you look at them wrong.
Extended O2 leads+$25Extra length on the oxygen sensor runs for aftermarket headers/downpipes.
Wideband O2 + ECU pigtailsComing soonShielded wideband run to the bung, plus double-branched ECU-end wires landed on A24 and D14 (or D10) — the pins your datalog reads. AEM-style controller link drops soon.See D14 on the P08 pinout card
New G101 ground+$30Fresh main engine ground at the thermostat housing — kills half the phantom electrical gremlins before they start.
Upgraded harness mounts+$45Billet-style P-clamps and bay hardware so the loom sits exactly where it’s supposed to, forever.
DIY Hippo zip ties+$10Hank’s own zip-tie kit — route it, cinch it, snip it. Budget mounting with mascot approval.

BUDGET LANE // RESTORE & REPAIR

Already have a harness? Let’s bring it back.

Not every D15B needs a ground-up build. Ship us the loom that’s letting you down — chalky plugs, cooked sections, mystery gremlins — and the bench goes through it end to end: continuity-tested, re-pinned, fresh seals, new braid where it’s tired. You name the budget, we tell you exactly what it covers, and it comes back plug-and-play. Back on the road, safe.

Step 1

Name your budget

Tell us what you can spend and what's acting up. The bench works inside your number — no surprise invoices, ever.

Step 2

Ship your loom

Box it up and send it to the bench. On 93 Octane? Loom shipping is on us — that's the membership talking.

Step 3

Plug and play

Continuity-tested, re-pinned, sealed and braided where it counts. Bolt in, key on — back on the road, safe.

93 Octane perk

Members ship their loom free.

Pit Crew 93 Octane members never pay to get a harness to the bench — box it, label it, done. One rescued loom usually pays for the membership by itself.

Built to order — every harness is loomed, pinned and continuity-tested by hand. Branch stock lengths are estimates until the bench measures your spec
